Title:
光ディスクの記録方法
Document Type and Number:
Japanese Patent JP4307135
Kind Code:
B2
Abstract:
PURPOSE: A recording method of an optical disk is provided to obtain an accurate recording property stably and restrain the occurrence of an error by determining an optimum recording laser power even though a disk has a mechanical variation property or a pickup has a rolling property. CONSTITUTION: Test data is obtained by using a laser power having a certain intensity on an optical disk, and test data is obtained by using the laser power whose intensity stepwise changes. A deflection is calculated from the obtained test data, and the obtained test data is compensated by using the laser power and the deflection in order to determine an optimum recording laser power.
