MANUFACTURING METHOD OF PHASE-CHANGE TYPE TAPE-SHAPED OPTICAL RECORDING MEDIUM, PHASE-CHANGE TYPE TAPE-SHAPED OPTICAL RECORDING MEDIUM, AND MANUFACTURING DEVICE OF PHASE-CHANGE TYPE TAPE-SHAPED OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a phase-change type tape-shaped optical recording medium with less cupping of a tape edge.;SOLUTION: The manufacturing method of the phase-change type tape-shaped optical recording medium provided with a recording layer on at least one principal surface of a flexible supporting body has a recording layer forming step for forming the recording layer having a phase-change type optical recording material whose phase is changed between a crystalline phase and an amorphous phase and an initialization step for irradiating the recording layer with a laser light so that the amorphous phase exists more than the crystalline phase in both end parts in a tape width direction as compared with a center part in the tape width direction.;COPYRIGHT: (C)2008,JPO&INPIT
