  • This graphic demonstrates some of the visible features  of a CD-R, including the lead-in, program area, and lead-out. A microscopic spiral of digital information begins near the disc's center and progresses toward the edge. The end of the data region and the lead-out can actually be anywhere, depending on how much data is recorded. Data-free areas of the disc and silent portions of the spiral reflect light differently, sometimes allowing track boundaries to be seen

Compact Disc Recordable         
<storage> (CD-R) A write-once version of CD-ROM. CD-Rs can hold about 650 megabytes of data. They are very durable and can be read by normal CD-ROM drives, but once data has been written it cannot be altered. Standard prerecorded CDs have their information permanently stamped into an aluminium reflecting layer. CD-R discs have a dye-based recording layer and an additional golden reflecting layer. Digital information is written to the disc by burning (forming) pits in the recording layer in a pattern corresponding to that of a conventional CD. The laser beam heats the substrate and recording layer to approximately 250 C. The recording layer melts and the substrate expands into the space that becomes available. {Phillips: New Technologies (http://www-us.sv.philips.com/newtech/cdrewritable.html)}.

CD-R

CD-R (Compact disc-recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times.

CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs.
