The OB III defines CD-RW media in terms of physical characteristics and in terms of playability and recording characteristics. Laser write strategies are defined, allowing CD-RW drive manufacturers to produce drives that can read this new CD media." So there are physically different CD-Rs, and the drive will treat them accordingly. The short/long strategy refers to the timing when switchin on/off the laser to write the CD. And http://www.cd-info.com/CDIC/Technology/Terminology.html#phthalo "phthalocyanine An organic dye used to form the data layer in some CD-Recordable discs. Mitsui Toatsu Corporation holds the patent on this dye, but has licensed its formula to some other manufacturers." And finally if you would like to know after which time you can expect the data on your CD-Rs to start rotting: http://www.cd-info.com/CDIC/Technology/CD-R/Media/Longevity.html Cheers, Helmut. +----------------+ | Helmut Walle | | [EMAIL PROTECTED] | +----------------+
