What is the difference between blue ray and DVD?
Blu-Rays are used only for high definition. Blu-Rays hold up 5 times more data than a DVD can hold. Blu-Rays have capabilities that are way ahead of DVDs, such as accessing the bonus material while watching the movie

There are a number of differences, some of which are technical, and I can't explain those to you. For example, the formatting or coding on the disc is different, and that's Greek to me. But I can tell you a few things. First of all, they both should play in your DVD player. Almost all DVD players th…ese days will play VCD's. The catch is, if you have an expensive DVD player, it often will not play homemade VCD's. Ironally, cheaper DVD players almost always will. Next, DVD's hold more data, so they are often much better quality. DVD movies are released on .. well.. DVD's .. which can hold anywhere from 4.7 to upwards of 9 GB of information. VCD's on the other hand, are written on CD's, which can only hold up to 700 MB of data (less than 1 GB). VCD is basically a format which came before DVD and was not very successful (at least in the USA), so they never really took off, but they were very successful in some other countries, such as Japan. So we don't see VCD players for sale very often, but like I said before, most DVD players will also play VCD's. One other thing is, VCD's are not too hard to make. Software is easy to find. Even free software, for making VCD's (if you have a computer and CD burner). You can also make VCD photo slideshows with music and pictures etc., fairly easily. Answer May I also add: VCD stands for 'Video Compact Disc' and basically it is a CD that contains moving pictures and sound. If you're familiar with regular audio/music CDs, then you will know what a VCD looks like. A VCD has the capacity to hold up to 74/80 minutes on 650MB/700MB CDs respectively of full-motion video along with quality stereo sound. VCDs use a compression standard called MPEG to store the video and audio. A VCD can be played on almost all standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder / player. It is also possible to use menus and chapters, similar to DVDs, on a VCD and also simple photo album/slide shows with background audio. The quality of a very good VCD is about the same as a VHS tape based movie but VCD is usually a bit more blurry. If you want better quality checkout SVCD,CVD or DVD. I wish to share my layman knowledge. VCD & DVD differ in Quantity of DATA, Quality of Sound and Image.50 Frame per second as a TV, and Height to width ratio 4:5 (Nearest to 35mm Movie). VCD takes a scan similar to VCR/VCP that has 200 vertical lines. DVD whereas have 550 or so.Sound stored in the time gap between frames Fly back (I think like Teletex, in gap between 2 frames)in real to lag 1/50 sec so as to get a continuity between sound bits. Sound in Digital Versatile Disc (DVD) is stored in MP3 Format. DVD has smaller track, get scratches easisy. DVD Format can be converted into AVI (ripped to any size 300:400 like that, and frame rate, generally 30 frames per minute, and recorded in DVD Disc as a movie that takes 2 1/2 hrs. needs a space of more than 700 MB, and require a DVD to store.Ordinary DVD cannot play. It reqires a Computer and Monitor or LCD TV that functions as a comp. monitor.can play it. Sound is compressed in both. Eg. a song of 5 minutes takes much less in MP2? format in VCD. Whereas 50 MB at 1400KB/second to make MP3. Combining sound and image in a digital mixure in sequence of time,Red,Green,Blue,Sound Track,Left,Right etc. Since Man cannot hear even 100 KB.frequenzy of 1400KBPS is Downsized to 120KBPS in stereo, compresses it to 4 MB. In Digital Technology variable frequency reduces it further. Now the trend is getting oriented into new Hi-definition generation in 9:16 Format(Nearer to 70mm format in proportion and 2MB, but a bit less than 35 mm projection that makes 2.5 MB eqv.) Next Generation may Windows concept. Suppose, A room has stationary & moving objects in a scene covering one minute (eg. Closs up,no zoom no camera movement)Only moving things require transition. Background can be freezed for all the frames. now you got the point, a movie that takes 1.5 GB in DVD,1.2 GB in VCD (require 2 discs), 750MB in AVI (require 1DVD) can be ripped into 500 MB that compromise near to DVD quality in single CD ( Full Answer )
Dvd-r is a format of DVD to be burned The DVD +r is considered slightly more compatible with DVD players and more reliable for computer DVD players www.Ricoh.com might be able to shed more light on this.
They use the same technology and disc size. They differ in how dense the tracks are printed onto the disc and the format. The recorder and players have to have different lasers, to be able to read the data. DVD players are backward compatible with CDs.
Video Compact Disc (VCD) has the picture quality of a VHS tape andhold about 74 - 80minutes of video. Digital Versatile Disc (DVD)processes a higher quality picture and holds more than two hours offilm on one disc.
Answer Data on a CD is written is form of small dots. A laser is used in CD drive to read data from CD. The light reflected because of the dots on the CD is translated to 1's and 0's. The difference between a DVD and CD is that DVD uses a more concentrated laser beam. This allows it to read very ve…ry small dots. Because the size of the dots is reduced we can save more data on DVD. Beyond little microdots, the big difference between DVD's and CD's is storage Capacity. CD's (compact discs) can hold between 640 - 700 MB's (megabytes) of information on a single disc. DVD's (Digital Video Discs) can hold 4.7 GB (gigabytes) of information on a single layer disc, and 8.5 GB on a dual layer disc. Beyond that, CD's hit the consumer market in 1983, and used a laser to read the media (disc) instead of magnetic technology. The standard amount of audio (time) on a CD with CDA sound files (compact disc audio) was approximately 72 minutes. Today, MP3 music files are about 1/10th the size of CDA audio. ***This unofficially works out to 10 MB per minute of audio with CDA, and 1 MB per minute of audio with MP3.*** Beyond all those specifications, there is an old technology called Laser Disc, which was almost the same size as an LP (the big ones) record, but also used laser. Based on the the technology that would bring us CD's, the laser disc provided more data storage than a typical CD due to more surface area to write to. This technology was short-lived vs VHS due to the high cost. Even though the discs themselves were cheaper to produce, the equipment required to play cost significantly more than equivalent VHS players. In the future, HD DVD and Blue Ray technology will rerevolutionize laser technology. Future High Definition Television programs will be shown in 720p, 1080i or 1080p. These video qualities make watching Television as though it's photographic quality instead of dithered like current 480i. The capacity for HD DVD is about 35 GB's per dual layer disc, and Blue Ray is about 45-50 GB's per disc (unofficial specifications from respective Mfrs.) ( Full Answer )
HD DVD and Bluray were competing high definition disc formats. In 2009 HD DVD was withdrawn from sale as it became apparent that Bluray had won the HD disc battle. The two formats are not compatible so HD DVDs can only be played on an HD DVD player.
The main difference between a CD and a DVD is amount of storage space. A CD generally holds 700 MB and 80 minutes of sound (tracks, speech and the like). A DVD generally holds 4.7 GB (Thats 4700 MB, and a singlelayer DVD. Doublelayered hold up to 8 GB, while doublesided and doublelayered DVDs h…old up to 17 GB.) They also use different types of readers (Disc drives). Most newer DVD drives are universal and can also play and write to normal CDs.. ( Full Answer )
dvds are a standard definition media that stores sd video. Blu-rays are the next gen media for high definition video. also, blu-rays have 7.1 surround sound and dvds have 5.1 surround sound so blu-rays are better. also blu-rays are more scratch resistant than dvds. blu-rays can store more v…ideo and special features than dvds. blu-rays are more robust. blu-rays are more expensive blu-rays are rarer than dvds. ( Full Answer )
VHS (Video Home System) uses magnetic tape in a cassette. DVD (Digital Versatile Disc) uses discs which are read by a laser light.
Blue Ray has almost double the lines of resolutions as HD-DVD, so therefore, double the picture quality. Actually, Blu-Ray is high definition (HD). But if by HD you meant the HD DVD, those are discontinued
CDs, DVDs and BluRay discs all work in similar ways. The primary difference is the data density on each disc. CD is the lowest density. A DVD can store several times the amount of data on the same surface area and BluRay will store several time the amount of a DVD.
The main difference is the color of the laser used. Regular DVD players have used the traditional red laser, whereas the new Blu-Ray DVD players use an innovative blue laser. So what's the big deal? The primary difference is that blue light has a shorter wavelength than red light and thus allows …the capability of faster speeds, more data storage, advances in miniaturization, and improved efficiency overall, among others.\n. \nThe blue laser light is emitted by GaN semiconductors, which are very expensive to produce and extremely rare.\n. \nThe first blue laser was produced by Dr. Shuji Nakamura in late 1999 in Nichia Chemical Corporation Laboratories.\n. \n_________________________________________________________________________________________\nPicture resolution. A regular DVD player in the U.S. is what's called an NTSC player and has 525 lines of resolution. The HD DVD has 700 to 1080 lines of resolution, depending on the way the disk was burned. ( Full Answer )
The difference is that the Blue-ray player records info in blue rays which have a shorter wavelenght so they can record and improve sound and picture. The DVD player records in red rays which have a longer wavelnght so picture and sound are watered down.
CDs have a storage capacity of around 700MB whereas standard DVDs can store 6 times as much information - around 4.5 GB - or even more on double layered DVDs. This means that video content (around 3GB for a movie) will fit onto a DVD but would be too large for a CD.
\nThe difference between a CDROM and a DVD is not only in the type and size of the content. On CDs, there is written, usually the word CD and some order things. And, on a DVD, there is DVD written on it. Although, the best way to tell is to put it in your computer and check the total size of the dis…c. DVD will show as 4.5 Gib or 8.7 Gib and CD will show as 690MB (more or less). ( Full Answer )
CD is compact disk or optical disk where you have the storage capacity of 700 MB(80 minutes of audio)DVD is digital versatile disk where you have the storage capacity of 4.7 GB.(6 times of CD)
CD and DVD are 2 different types of media storage. DVD's can hold far more data on them due to the fact that the laser used to read them is much narrower. CDs can hold a maximum of 700mb or about .7GB For DVDs, there are currently two types available:. DVD_+R/RW which holds 4.3 Gb. DVD-+R/RW …dual layer (2 layers of silicon to put data on inside the disk)which holds 7.2 Gb. There is also writable disks that hold 4.7Gb and also, some company's disks can hold more than others but the difference is minimal . There is also Blu Ray disks now that can hold between 50Gb and 80Gb ( Full Answer )
Blu-Ray is for HDTVs. They can hold up to 5 times more data than a DVD can hold. Blu-Rays are also more resistant to scratches and harder to break than DVDs
\nIt's not called "Blue-ray DVD" it's just called "Blu-Ray" and it is just a DVD that is able to hold a longer movie with better audio and picture quality for High Definition movies.
The difference is the disk, dvdr has a slightly smaller disk, to most you wont even be able to see it, the fact of using dvd disc's means that youll be able to have the bigger disc's meaning better memory as it has more space to hold more!
In terms of storage capacity, DVD+ and DVD- are identical. However, DVD+ and DVD- have slightly different coding formats.
Blu-Rays are the highest HD out there yet and they will only play on Blu-Ray players which will only work on HDTVs. DVDs are not high definition, but they are compatible with Blu-Ray machines.
Blu-Rays are not DVDs. Blu-Rays will only work on Blu-Ray players. They are for high definition TVs only. A Blu-Ray disc can hold up to a maximum of 50 GB, which is 5 times more data than a DVD

The difference between a DVD and a CD is that the former can storevideo and image files whereas the latter stores audio and imagefiles. Another difference is that the storage space on a CD is 700MB while a DVD stores about 4.7 GB of data.
Blu-Ray discs can hold up to a maximum of 50 GB of data and that is 5 times more data than a DVD can hold
Blu-Ray discs can only be played on HDTVs. Blu-Rays hold up to 5 times more data than a standard DVD. Blu-Rays also have a special hardcoat layer on the bottom that makes it more resistant to scratches. And Blu-Rays have better image and sound quality than a DVD does. Blu-Ray players also have a bac…kwards compatability that allows it to play regular DVDs Blu-ray is a HDTV formatted DVD system. can a regular DVD be played on a blu ray player? With a blu ray disc you are able to have better sound quality, a higher resolution resulting in better graphics, and because of the larger storage capacity, more special features. Blu rays usually cost more, but many people find them worth the additional investment. ( Full Answer )
Up-converting refers to the scaling of a standard definition signal such as a DVD output to an HD video format. It does NOT make a DVD into a high definition player and the image quality is not improved with the conversion. A Bluray player will play Bluray discs in HD quality as Bluray discs stor…e HD video content. ( Full Answer )
Yes Most will also upscale the DVD and provide better than 480i or standard resolution. PS3 blu-Ray and all Sony Blu-rays will have near 1080p upscaling of the DVD
as name drive basically dvd is "digital video disk "and cd is compact disk .in dvd a no. of files (movie ,data etc)are stored but in cd less amount of data is stored in compact size.
In short, Data DVD only can be played in computer, and DVD can be played on both DVD play and computer.
Blu-Ray is for HD only. They can hold up to 50GB of data which is 5 times more than a DVD. Blu-Rays have numerous abilities that DVDs can never have, such as accessing the bonus material WHILE watching the movie
There are some major differences between Blu Ray players and DVD players. Among the most important is that you cannot play a Blu Ray disk on a regular DVD player.
A DVD-RW disc is a rewritable optical disc with equal storage capacity to a DVD-R, typically 4.7 GB. RW discs are can be written to and erased many times, they are both readable and writeable. Pre-recorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. S…uch discs are known as DVD- ROM , because data can only be read and not written nor erased. ( Full Answer )
HD DVDs and BluRay DVDs have some things in common. However, BueRay discs can hold more information since they have a tighter track. BueRay discs have a thinner disc, with a special coating to protect them. This makes BluRay more expensive.
i don't know but maybe you could ask a teacher or an expert or you parents. hope this helps!! ;)
CD is mainly used for distributing music,while DVD can store more data and used to distribute movies and BLUE RAY can hold up to 50GB.
Blu-Ray DVDs are for HD TVs and require a Blu-Ray player or a PS3. The sound is improved and the crispness of the picture (graphics) is noticeably improved.
DVD r the R stands for recordable. DVD rw the rw stands for re-writable. Both types let you record, the rewritable lets you use them multiple times. The - and + symbol standards were developed by different companies and are noting single layer recording or multilayer recording styles For pre-r…ecorded discs that you are not able to record with there are two possible abbreviations DVD a single layer disc which contains data and cannot be used to record DVD+ a multlayer disc which contains data and cannot be used to record With discs that you record for yourself there are typically four abbreviations: DVD-r a single layer disc that can be recorded once DVD+r a multilayer disc that can be recorded once DVD-rw a single layer disc that can recorded, erased and reused DVD+rw a multi layer disc that can be recorded, erased and reused In addition any of them can be designated dual layer which doubles the storage area and will contain the dual layer notation somewhere on the disc usually near the DVD+/- symbol. While most modern players are capable of reading and playing from all 12 DVD types; DVD burners that create discs are often very picky about which types it is able to burn. Depending on the brand manufacturer and the age of the player it may only be capable of creating some of the recordable types (a burner is typically either + or - and than it may or may not be able to handle dual layer on top of that) The instructions for the player and/or burner should note which DVD formats are supported for playback and a separate list of which are supported for DVD burning Beyond those physical disc types there are also differences in region coding. Different countries and/or continents have regional codes noted separate from the DVD symbol. If your player and/or recorder are region coded than only discs which match your region code will function. This most often only effects pre-recorded movie discs and not recordable formats and it is becoming far more common for newer DVD players to be region free. If your player and/or burner have region coding this designation and which regions it supports should be explained in the documentation. This region code rarely effects computer DVD drives and is usually a modification on cheaper model stand alone DVD players to discourage cross region pirating and control distribution of films.

A DVD is a disk that is coated in a layer of material, that material is physically changed using a lazer to make dents in the material. This represents the 1s and 0s by making into a dent or no dent. A USB drive is a small stick that has billions of tiny cells that can be manipulated to allow ele…ctricity through or not. The computer can send some electricity to it in a way to either turn it on or off. Then it can read it by trying to send electricity through it. If you mean by how much data they can store a DVD normally holds 4.5 GBs while a USB drive can normally hold up to 256GBs [although Victorinox has one with a capacity of 1TB (1024GB) ] Mostly depends on how much you want to pay. USB drives can be more expensive but last much longer and you can change what is on them very easily compared to a DVD. Additionally DVD is Digital Versatile Disk and USB is Universal Serial Bus.

Depends on what you mean by "zip". A zip file is a file of data that has been compressed to maximize storage space. A zip disk was a removeable magnetic recording medium that held more than a floppy disk, but less than a DVD. A DVD is an optical medium. You can put zip files on a DVD, but t…hey will not be playable on a DVD player, since software is required in order to "unzip" them. ( Full Answer )
Blu Ray players are the upgrade to the DVD player, and as such offers better picture resolution for the viewer. An important distinction is that Blu Ray players can read and play DVDs but DVD players cannot read and play Blu Ray discs.
HD DVDS are DVDs that can be played on high definition TV players. The regular DVD can be played on any TV and is not in the same definition as the HD DVDs.
Blu Ray players will play DVDs and Blu Ray discs. Blu Ray discs often have interactive features and 1080p HD picture, while DVDs do not. Blu Rays can hold a much larger amount of information, which allows for these features. Blu Ray players also cost much more than DVD players.
There are a few differences between a DVD player and a Blueray player. For instance, Blueray players and Blueray discs have higher picture definition and quality. The Blueray disc is also capable of holding more information. DVD information is written on the disc with a red laser, which a blue la…ser is used for Blueray discs. Blueray discs are also studio quality while DVDs are not. ( Full Answer )
Blu-ray discs have tighter track pitches making them able to hold more information than an HD DVD of the same size. Blu-ray discs also have a thinner surface layer than HD DVD discs. This makes the laser able to focus better.
Blu-Ray technology is the successor to DVD technology and is significantly more powerful (similar to DVD being the successor to the VHS format). This allows films on Blu-Ray to look crisper, sharper, and generally higher quality. DVDs remain popular with many people who prefer a lower price to a bet…ter picture. ( Full Answer )
Blu Ray Discs are able to hold more data which in turn means it is capable of holding HD copies, which if you have a HD TV will mean a greater quality viewing. Regular DVD just has normal resolution although the difference can only be seen if the TV is not an old standard one.
The number of byte that a blue ray DVD holds depends with the size.The 4.7 GB usually holds a total of 5.04659e9 bytes.
A DVD+R can only be recorded once. A DVD+RW can be recorded onmultiple times until the disk is full. You add data to a DVD+RW,but you can't remove previously recorded data.
