<P>PROBLEM TO BE SOLVED: To provide an optical disk-recording method and optical disk apparatus, which enables accurate compensation without changing a basic waveform in downward compatibility for recording an optical disk for high linear speed at low speed in a variety of the optical disks with different recording film material and recording mechanism, and to provide the optical disk which enables easy compensation. <P>SOLUTION: The optical disk-recording method makes a recording waveform a multi-pulse, independently changes each of a rising timing and falling timing of a first pulse (pulse width) depending on a preceding space length and recording mark, and changes a rising timing and falling timing of a last pulse (pulse width) under a fixed relation or independently depending on a subsequent space length and recording mark, while for a minimum mark for recording a single pulse, changing the rising timing depending on the preceding space length and recording mark and the falling timing (pulse width) depending on the subsequent space length and recording mark. <P>COPYRIGHT: (C)2010,JPO&INPIT |
