The "Blu" in blu-ray refers to a short-wave blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
Blu-rays are now standard media, overcoming DVDs. Blu-ray discs can also hold more information than DVDs, so it's possible to burn more high-quality music and homemade videos on a single Blu-ray disc than the antiquated DVD.
No, that's with all the ps3 discs. Its called BLURAY. That's another distinctive feature that distinguishes it from the 360. Its more scratch resistance and holds more space.
CDs and DVDs share the same physical format but the DVD stores more data that a CD. It does this a much finer set of optical tracks on the disc than the CD has. In a similar way, Bluray discs hold far more data than a DVD.
Bluray is the development of Sony. It was produced to support HD video and must be considered more of a development than an invention. There are numerous technologies that went into the format and each was developed or enhanced by different teams of engineers. The Bluray system includes the manufacturing process for the discs, data encoding, laser specification and more.
You can indeed make Blu-Ray discs that hold 35 GB of data or more.
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.
The digital discs that can hold the most information currently are the second generation, double sided DVD Random Access Memory discs. They are cartridge-based, and more recently, bare disc technology for data recording and playback. A standard DVD-RAM Version 2 disc holds about 9.4 GB of data. DVD-RAM bare discs are fragile however and do not guarantee data integrity. They also require a special drive.
Yes, it will hold much much much more than CD-RW discs.
Upconversion simply means that all of the components you have plugged into the back of the receiver will be upconverted to an HDMI output so you only have to run one HDMI cable between the receiver and the display. This makes for a much cleaner installation and the receiver will handle the switching of different inputs for different functions. Upscaling on the other hand is quite different because it not only combines all of your inputs into one output cable, but it also increases or “upscales” the resolution. For example, upscaling will take all of your analog signals coming into the receiver and increase the resolution to 1080i/720p or even 1080P for optimal viewing on a HD display. *run976*
North America is classed as region 1 for DVD, Bluray and games coding. The codes are there specifically to prevent discs from one region being used in another. Region 2 covers Europe. There have been a handful of DVD players that did not check the region code and would play discs from any region. Bluray players appear to be far more tightly controlled and it is very unlikely that any commercially available player will allow the coding to be bypassed. It is possible that players can be modified to remove the coding restrictions but these are unofficial modifications, void warranties and cannot be guaranteed to work continuously. As frustrating as the region coding is, the easiest and lowest cost route to take is to buy discs intended for use on your own player. Note that as the region coding is a commercial protection, non commercial DVD and Bluray discs do not have the code and can be handled by any player. That is subject to the player and the television handling European 50Hz content. The US normally uses 60Hz video so there is still no guarantee that your specific setup will work. It's a case of studying the manuals to make sure.
It is impossible to tell what holds the discs together without more information. Please be more specific in your question. There are many different types of disks, all of which would be held together differently.
Could be nothing more than the Bluray DVD's that you're watching aren't encoded in 5.1 surround.
