Information recording method and optical disk apparatus |
摘要 |
A method and apparatus for recording information which presume a recording state from reflected light during recording to achieve a stable recording quality. When recording information on an optical disk by irradiating laser light with a specified record power (Pw) to form a train of record pits, the recording is performed while forcing a value (CF) of B/Pw<SUP>2 </SUP>to be kept substantially constant, where B is the value obtainable by sample-hold of a reflection light amount upon irradiation of the laser light with the specified record power (Pw). Performing the recording in this way makes it possible to realize the recording quality with increased stability. In addition, upon alteration of a tilt angle, arithmetic processing is redone to thereby achieve the stability-enhanced recording quality.
