METHOD FOR RECORDING OPTICAL DISK, OPTICAL DISK AND OPTICAL DISK APPARATUS |
摘要 |
PROBLEM TO BE SOLVED: 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. SOLUTION: 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.
