Abstract

High-density recording using a SeInSb alloy film is now possible. Recordings with mark lengths as small as 0.8-0.9 μm yield good quality signals. This medium also demonstrates good performance, as evidenced by its long-term stability and a high number of write-erase cycles. It is also clear that the avoidance of waveform distortion is essential for the high-density recording of actual signals.
