Abstract
A fast data transfer and high density recording was realized, using a 30 mw visible laser and a GeTeSb phase-change medium. Fast laser power control technique was used for suppressing the laser light power fluctuations, and a RIN of -123 dB was obtained. Using this technique, a CNR of 56 dB and an erase ratio of 25 dB was obtained with a mark pitch of 1.25 micrometers for an overwritable phase change medium.
