OPTICAL DISK RECORDING METHOD AND OPTICAL DISK DEVICE

摘要

PROBLEM TO BE SOLVED: To control recording power by matching a write strategy with a recording linear velocity change in a zone to secure quality when a plurality of zones are provided in the CAV recording of an optical disk.

SOLUTION: The reliability of information is secured by optimizing a write strategy (pulse timing and power ratio) based on the highest recording linear velocity of each zone, and controlling power setting in each zone so that a relation between a recording linear velocity V and recording power Po is Po=CV (C is a coefficient obtained from a relation between Po and V at a zone end point).
