Paper Abstract

Direct overwriting is studied for both magneto-optic and phase-changing optical disks. One of the most promising approaches is magnetic field modulation on a magneto-optic disk using a floating magnetic head, providing over 15 Mbps data transfer rate. Another candidate is one-laser-beam overwriting on a high-speed crystallizing material such as InSeT1Co. The present status and future possibilities of these two approaches are presented with other approaches for direct overwriting.
