摘要： A recording method for an optical disc having at least three recording layers (11, 12, 13, 14), in which test recording areas are formed in the odd-numbered recording layers (11, 13) and the even-numbered recording layers (12, 14) in positions that are mutually non-overlapping in the thickness direction of the optical disc, the test recording areas in the odd-numbered recording layers are formed in positions mutually aligned in the thickness direction, and the test recording areas in the even-numbered recording layers are formed in positions mutually aligned in the thickness direction. The time for test recording for determining the optimal recording power can be shortened.

摘要： In a recording method for recording information on an optical recording medium (500) according to the parameters of a write strategy by repeatedly recording (S23) a certain amount of information onto the optical disc (500) and entering a standby state (S22) in which recording is suspended and data are stored in a buffer memory (190), during an interval while recording is suspended, the information recorded just before is reproduced, the quality of the reproduced signal is measured (S25A), and the write strategy is altered as necessary (S25C) to obtain consistent recording quality. Only one correction is made per suspension period. Consistent recording quality is thus obtained despite changes in the recording position on the optical disc or changes in recording conditions.

摘要： To adjust the parameters of a write strategy for recording data on an optical recording medium, the jitter value of a reproduced signal obtained from recorded data is detected. If the jitter value exceeds a prescribed threshold, a write strategy parameter having a comparatively small effect on the jitter value is adjusted, and subsequent data are written on the recording medium using the adjusted parameter. Parameters are selected for adjustment in ascending order of their effect on the jitter value. Stable data recording can thereby be carried out without significant jitter degradation.
