Paper Abstract

A new phase-change disk that has a double-reflective-layer structure and a recording film that contains a high-melting- point component is examined. With this medium, 105 overwrites with a little mark-edge jitter in the mark-edge recording scheme and a long storage lifetime have been achieved. The beneficial effects of the double-reflective- layer structure and the high-melting-point component in reducing mark-edge jitter and their mechanisms are discussed.
