CD-RW Technology

CD-RW drives use a technology known as optical phase-change. It does not use magnetic fields like the

phase-change technology used with magneto-optical technology. The media are generally distinguishable

from CD-R discs by their metallic grey color. The basic structure of the discs, however, is the same as a

CD-R disc but with significant detail differences. A CD-RW disc's phase-change medium consists of a

polycarbonate substrate, moulded with a spiral groove for servo guidance, absolute time information and

other data, on to which a stack (usually five layers) is deposited. The recording layer is sandwiched

between dielectric layers that draw excess heat from the phase-change layer during the writing process.

In place of the dye-based recording layer on a CD-R disc, CD-RW commonly uses a crystalline compound

made up of a mix of silver, indium, antimony and tellurium. This mix, when heated to a certain

temperature and then cooled becomes crystalline, but if heated to a higher temperature it becomes

amorphous when it cools down again. The crystalline areas allow the metallized layer to reflect the laser

light better while the non-crystalline portion absorbs the laser beam, and is therefore not reflected.
