Title:
METHOD FOR RECORDING OPTICAL DISK, OPTICAL DISK AND OPTICAL DISK APPARATUS
Document Type and Number:
Japanese Patent JP2000195055
Kind Code:
A
Abstract:
To prevent signals recorded to an optical disk from being deteriorated even when the optical disk has a narrowed track pitch and even when a circumferential light of an optical beam spot partly erases record marks of adjacent tracks.
An optical disk 400 is provided with an area for storing the number of recording times of a manage area, so that signals recorded to the manage area are rerecorded for every predetermined number of recording times. According to the method for recording the optical disk, even when a beam spot becomes off track thereby partly erasing signals of an adjacent track, information of the adjacent track is reproduced immediately after recorded, and rerecorded to the adjacent track in a constitution of the apparatus.
