A recorder encodes (or burns) data onto a recordable CD-R, DVD-R or DVD+R disc (called a blank) by selectively heating parts of an organic dye layer in the disc with a laser in its write head. This changes the reflectivity of the dye, thereby creating marks that can be read as with the "pits" and "lands" on pressed discs. The process is permanent and the media can be written to only once.

Love to read all these expert answers... some parts are good...some are blowing smoke. The CD is recorded in concentric circles and not a track that you could unroll as one suggested (like a phonograph record). They make cool wind chimes (all those AOL gitchya disks) when you stick them in the micro for a few secs, and hang them from a coat hanger with fishing line. People pay good money for those at the local flee market!!!, but they can only hold 800 megs with over/burn. Gona leave it to the "experts" to explain how a CDRW can fill in those pot holes so it can be used again!?!?

It's etched onto a reflective surface (usually the underside of the label) by a laser beam. The laser is a very thin beam and can make billions of digital impressions on one CD. This is why you can scratch the non-label side of a CD and it will usually still play, but if you scratch the label, you're screwed.

They have a system that is very like that on a record. If you could uncoil the track system on a cd it would be 3 miles long. It is basically a set of dot dash dot and when the laser hits it, it changes what can be read.

The information on a CD is digital. Digital information is very small and you can pack about 700 mega bytes on a Cd. You can store more text on a cd than photos or music.

It's called a laser you brain child. It picks up the microscopic info that is in graved on it. It's pretty much like the records of old, but works on a microscopic level.

Holes are burned into it with a laser. Then they reflect light and represent either a zero or one. And thats the truth!
