Title:
光ディスク装置、その制御方法、およびこの制御方法をコンピュータに実行させるプログラム
Document Type and Number:
Japanese Patent JP4551597
Kind Code:
B2
Abstract:
Optical disk device, in which a tracking adjustment system and sled adjustment system are controlled independently, has offset value acquisition capability, which detects the tracking drive signals output from tracking adjustment system for one lap around optical disk and acquires multiple tracking drive offset values. Such device also has offset representative value computation capability, which computes an offset representative value from multiple tracking drive offset values, as well as an offset value comparison capability, which compares the offset center value in the state in which no tracking adjustment control is done, and the offset representative value, as well as a sled drive decision means capability, which decides the drive of sled adjustment system 36 based on the comparison result.
