Abstract:
Single-beam overwrite performance of 5.25 inch diam. In 3 SbTe 2 phase-change optical disks was examined at a constant angular velocity (CAV) of 1800rpm (υ=5-11 m/s). We obtained overwrite with a new erase mode and achieved a large erasability of more than 35 dB and a carrier-to-noise ratio ( C / N ) of more than 50 dB. This good erasability was found to be supported by a new erase mode called the “winking erase mode”. From TEM observation of the overwritten structure, the erasing mechanism was discussed and the physical model due to the growth of crystalline grains was proposed.
