The compact disc (CD) was developed by Philips and Sony in the late 1970s. The technology was officially announced in 1979, and the first CDs were released to the public in 1982. The CD was initially designed for audio storage but eventually evolved to hold data and video as well.
Is a CD-rom the same as a DVD-r?
The term "CD" means Compact Disk..so there really is no product just called a "CD"..it must be CD-ROM, CD-R, CD-RW,etc. "CD" means the same thing in all categories. The difference lies in the letters after CD, for example CD-ROM mean Compact Disk Read Only Memory which means you cannot write to it you can only read it as in play a movie. CD-RW, means Compact Disk Read/Write, which means you can read and write to it. Hope this helps.
They are totally different. You cannot play a CD-ROM in a CD/DVD player; but, depending on your computer software, you can play a CD on your computer.
In other words, a CD-ROM can only be used in a computer, but a CD can be used in a CD/DVD player and on any computers that have software for playing CD's.
Why is CD-ROM drive important?
It is a mass storage device that is where all information is really stored. PC must be able to store and retrieve this information for it to function as indented working on stored data.
CD-ROMs are read-only discs designed for storing data permanently, while recordable CDs (CD-Rs) allow users to write data once. Rewritable CDs (CD-RWs) can be erased and rewritten multiple times. DVD-ROMs function similarly to CD-ROMs but have greater storage capacity, while recordable DVDs (DVD-Rs and DVD+Rs) can be written once, and rewritable DVDs (DVD-RWs and DVD+RWs) can be erased and rewritten multiple times.
Help my CD player will not work on my thomas pacconi classic phonograph combo?
If your CD player on the Thomas Pacconi classic phonograph combo isn't working, first check if it's properly connected to a power source and that the power switch is on. Ensure the CD is clean and free of scratches, as this can affect playback. If the issue persists, try resetting the device by unplugging it for a few minutes, then plugging it back in. If none of these steps work, it may require professional servicing.
No. Technically, a true CD is a "read-only" media - that is, once the data has been put onto it during manufacturing, it cannot be altered.
Now, there are several types of technologies that do allow you to write data onto what looks to be a CD. CDs marked as "CD-R" or "CD+R" are referred to as "recordable" CDs. Using a special kind of CD player (typically found on a computer these days), you can write data ONCE to such a CD-R (or CD+R), but cannot erase anything already written.
Another type of technology is the CD±RW, also known as the CD Rewritable. This form of CD allows you to write multiple times (and, also erase), just like a hard drive.
Modern computer CD (or DVD) drives are mostly of the ±RW form, so most people can use a normal CD, the CD+R, the CD-R, or a CD±RW disc in them. Remember, each type of disc is different, so you must buy the disc media of the type you want to use (i.e. you can't use a CD disc as a CD-R, you must buy a disc specifically labled "CD-R")
What is a CD is CD a electric disk or magnetic disk or a electromagnetic disk?
A CD, or Compact Disc, is an optical disc used to store digital data. It primarily relies on laser technology to read and write information, making it neither an electric disk nor a magnetic disk. Instead, it utilizes optical encoding, where data is represented by tiny pits on the disc's surface that are read by a laser.
What year did the digitally recorded disc become available?
I dont know when, but the Sony Co. have the patent of Digital Optic Disc. Maybe you can reach this question on the site of Sony.

How do you format Verbatim DVD-R discs?
To format Verbatim DVD-R discs, insert the disc into your computer's DVD drive. Open your operating system's disk management tool—such as Disk Utility on macOS or File Explorer on Windows. Select the DVD-R drive, right-click, and choose the format option, ensuring to select the appropriate file system (usually ISO 9660 or UDF for DVDs). Follow the prompts to complete the formatting process. Note that DVD-R discs are typically write-once, so formatting will erase all existing data.
A DVD is relatively portable but I suspect you mean a DVD player? In which case it's only portable if it's a portable DVD player.
