I'm not necessarily sure that they require a different wavelength of light (at least not to read). I do know they operate on a different principle than CD-Rs. CD-RWs are a phase change medium, in that the surface that you write to has 2 (?) states, one that does not reflect light, one that does. So when you write to it you change it so that it's similar to a CD-R (in that some parts are reflective some aren't so you get the 1s and 0s). Erasing the disc changes is back to it's "virgin" state (not quite but close enough).rentagas said:CDRW's do not usually work in standard CD players because they require a different light (laser) wavelength to be read. They do work usually in DVD players.
The CD boost will play my TDK CDRW discs.
