RECORDING METHOD OF OPTICAL DISK, CONCERNED WITH IMPROVING REPEATED RECORDING PROPERTIES OF AN OPTICAL DISK WHILE MAINTAINING LOW JITTER PROPERTIES DURING A PEATED RECORDING PROCESS

摘要

PURPOSE: A recording method of an optical disk is provided to locate a rising edge of a multi-pulse after a reference clock which comes next to the first pulse. CONSTITUTION: By moving a rising edge of a multi-pulse(MP) to the right from a reference clock, an additional cooling time is created as much as a distance which the multi-pulse(MP) moves except a cooling time created before a next 1T clock from the first pulse(FP). The additional cooling time is 10 to 20% of a 1T clock. To compensate for an increase of the cooling time, a width of the multi-pulse(MP) gets bigger than other pulse. The width of the multi-pulse(MP) is 40 to 50% of the 1T clock.
