CD-R

CD-R #3

Because of these traits, they are usually used for music albums or audio recording of some kind, as they can't be overwritten. They are also cheap to produce, so they are very commercially viable. The main downside is that, like most writable media, the CD-R degrades over time, and the data becomes corrupt and unreadable.

CD-R #1

CD-R stands for Compact Disc - Recordable, and it was invented by phillips and sony. It is a variation of a Compact Disc, and is a WORM optical medium (Write Once Read Many). Unlike the CD-RW, once the CD-R has been written, it cannot be rewriten, although it can also be played on a wider variety of readers.

CD-R #2

Its Purpose is, as with all compact discs, to be able to play what it has stored within, but it also allows things to be recorded onto it (but only once). CD-Rs are usually able to store around 80 minutes of audio (about 700MB), but there are also discs able to hold 90 or 99 minutes(790 or 870MB).
