(CD-R) A write-once version of CD-ROM. CD-Rs canhold about 650 megabytes of data. They are very durable andcan be read by normal CD-ROM drives, but once data has beenwritten it cannot be altered.Standard prerecorded CDs have their information permanentlystamped into an aluminium reflecting layer. CD-R discs have adye-based recording layer and an additional golden reflectinglayer.Digital information is written to the disc by burning(forming) pits in the recording layer in a patterncorresponding to that of a conventional CD.The laser beam heats the substrate and recording layer toapproximately 250 C. The recording layer melts and thesubstrate expands into the space that becomes available.Phillips: New Technologies(http://www-us.sv.philips.com/newtech/cdrewritable.html).See also CD-RW and DVD-RAM.
