摘要： In a medium of the phase change type, a power ratio and modulation degree for use in recording are determined from a recommended pulse width value in the recommended write strategy parameters recorded in the optical disk, the recommended power ratio value, the recommended recording power value, and the characteristics of the optical recording device, and recording is carried out on the optical disk according to the power ratio value and modulation degree value thus determined. Optimal recording can be carried out even on an optical disk for which the optimal write strategy information has not been determined in advance, without the need to store write strategy information suitable for each and every optical disk.

摘要： A recorded area is reproduced during a suspension of a recording operation; when degradation of the recorded signal is detected (S4, S5) by the signal quality detection means (16), a tilt adjustment is performed in the recorded area, the signal quality of the recorded signal is detected after the tilt adjustment (S6), and if it is still degraded, a recording parameter is altered (step S7). The need to obtain tilt adjustment values for tilt corrections at a plurality of radial positions in advance is eliminated, resulting in reduced apparatus overhead and better recording quality.

摘要： According to a method for setting the laser beam power applied to reproduce information recorded on an optical disc, information recorded in a region on the optical disc is reproduced using three or more test reproduction powers (S22B), the number of reproductions until the degradation of the quality of the reproduced signal reaches a prescribed value is determined as the degradation number of reproductions (S22F), the relation between the test reproduction power and the degradation number of reproductions is approximated by a curve, and a reproduction power restricting the degradation of the reproduced signal quality to a predetermined amount or less over a certain guaranteed number of reproductions is determined (S25F). In optical reproduction from an optical disc on which information is recorded, the optimum power of irradiation for reproduction can be set, and degradation of the information due to the reproducing light can be prevented.
