Title:
RECORDING METHOD FOR PHASE-CHANGE TYPE RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2007188629
Kind Code:
A
Abstract:

To provide a recording method for a phase-change recording medium which allows formation and elimination of an amorphous mark to be easily carried out, even if a reflective layer is thin or not present, and without narrowing the range of available crystallization speed, in a rewritable phase-change recording medium.

This method includes a front low-power pulse radiation step arranged immediately before a leading pulse as a zone where recording power Pw is radiated for the first time, and radiating bias power Pb for a first set period yT; and a succeeding low-power pulse radiation step arranged immediately after the leading pulse, and radiating the bias power Pb for a second set period xT, wherein a relation between x and y satisfies 0.95≤x+0.7*y≤2.5, and a radiation period of a succeeding pulse as a zone where a high power energy beam is radiated following the steps is constituted so as to be from ≥0.5 T or more to ≤1.5 T.
