Title:
OPTICAL DISK AND OPTICAL DISK DEVICE
Document Type and Number:
Japanese Patent JP3948731
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk capable of accurately predicting the deviation of a recording position from a target position.
SOLUTION: When a prescribed reference mark is formed on the top position of at least one of addresses distributed to a specific area of a meandering track G, prescribed positional relation between a reference position in the meandering shape of the track and the reference mark position is obtained, and when a wobble signal from a specific area of an optical disk is compared with an RF signal by using an optical disk device, the delay quantity of the wobble signal can be detected, so that the deviation of the recording position from the target position can be accurately predicted.
