Patent ID: 8139456

Claim:
An optical recording method for recording information by directing laser light onto an optical recording medium according to a write strategy responsive to recorded data length, the write strategy including a plurality of parameters, the information being recorded on the optical recording medium by alternate repetition of a recording period in which the information, which has been externally supplied, written in a buffer memory, and is read from the buffer memory, is recorded and a suspension period in which recording is suspended, the optical recording method comprising: a step of controlling starting of the recording period and starting of the suspension period according to an amount of data in the buffer memory; a write strategy correction step of reproducing, during the suspension period, information that has been recorded in the immediately preceding recording period, and correcting a parameter of the write strategy, based on reproduced signal quality; a correction timing detection step of detecting a correction timing of the write strategy in the suspension period; and a step of performing recording during the next recording period, using the parameter of the write strategy as corrected in the write strategy correction step; wherein the write strategy correction step includes a quality measurement step of measuring signal quality of a signal recorded just before, and a write strategy alteration step of altering the write strategy, based on the reproduced signal quality measured in the quality measurement step; and wherein processing of the write strategy correction step in the suspension period is performed conditional on detection of the correction timing in the correction timing detection step; and wherein the correction timing detection step detects the correction timing when a setting correction interval has elapsed from starting of recording onto the optical recording medium or when the setting correction interval has elapsed from the most recent performance of the processing of the write strategy correction step; and the optical recording method further comprises a setting correction interval update step of altering the setting correction interval according to the reproduced signal quality measured in the quality measurement step.
