METHOD OF INITIALIZING PHASE-CHANGE OPTICAL DISK AND PHASE-CHANGE OPTICAL DISK |
摘要 |
A method of initializing a phase-change optical disk which is capable of preventing enlargement of an amount of jitter which takes place when the number of overwriting operations does not exceed several times. The surface of the phase-change optical disk, on which information signals will be recorded, is crystallized. Then, signals are recorded with marks and spaces in grooves along tracks of the phase-change optical disk so that initialization is performed. The initialization is performed in such a manner that the length of each of spaces is shorter than a shortest length of spaces of information signals.
