Paper Abstract

A microcellular recording film is proposed to prevent material flow due to multiple overwriting in phase-change optical disks. The GeSbTeCo recording film, divided into cells of approximately 20-30 nm in diameter, is prepared by sputter-etching using a Ti polycrystalline film as a mask. Reversible phase-change occurs in the microcellular GeSbTeCo film. Moreover, single beam overwriting is achieved at a linear velocity of 7 m/s.
