OPTICAL RECORDING METHOD, OPTICAL RECORDING APPARATUS, AND OPTICAL RECORDING MEDIUM |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide an optical recording method by which successful recording property is acquired ranging from low recording linear velocity to high recording linear velocity and further an overwrite property is maintained successfully. <P>SOLUTION: A first power ratio εl obtained by dividing a first erasure power Pel in the first recording linear velocity Vl to a recording layer 3 of an optical recording medium A by a first recording power Pwl; a second power ratio εm obtained by dividing a second erasure power Pem in the second recording linear velocity Vm by the second recording power Pwm; and a third power ratio εh obtained by dividing the third erasure power Peh in the third recording linear velocity Vh by the third recording power Pwh satisfy the relationship (Vl<Vm<Vh) in the formula(1): εh<εm<εl. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
