摘要： This invention provides accurate control of laser light power in a recording operation to achieve more stable recording operation. An optical disc drive in an embodiment of this invention monitors the power of laser light with a monitor diode and controls the laser light power based on the result of monitoring. The optical disc drive changes data transfer rate (recording frequency) depending on the disc radial position. The optical disc drive controls the gain of the monitor diode across the recording surface depending on the recording frequency. This control improves the accuracy in laser light power control to achieve stable recording operations by precise servo control.

摘要： Before new information is recorded on a comparatively deep recording layer in a multilayer optical recording disc, a predetermined target value of a reproduced signal parameter is read from the disc itself or from a separate storage unit, the recorded/unrecorded states of the shallower recording layers are determined, and the target value is corrected on the basis of these states. The correction is based on a predetermined difference in the value of the reproduced signal parameter caused by a difference in the recorded/unrecorded states of the shallower recording layers. The corrected target value is used in calibration of the recording power by means of a test write. This correction of the target value permits reliable recording on a multilayer optical disc without delaying the start of the recording process.
