Paper Abstract

We developed a phase change media that has less cross-erase at a track pitch of less than 0.6 micrometer. The phase change media has an absorptivity ratio Ac/Aa of 1.5 (Ac:absorptivity in a crystalline state, Aa:absorptivity in an amorphous state), while maintaining the rapid cooling structure. There was no significant cross-erase even at a track pitch of 0.52 micrometer. Feasibility of recording capacity of about 5 GB on a 120 mm disk has been confirmed.
