In a method for compensating recording power, being suitable for an optical disk apparatus, applying the WOPC therein, as a means for compensating recording power during recording operation, and also an optical disk apparatus applying the same therein, wherein the recording operation is interrupted, when a predetermined amount of data is recorded continuously, to determine the recording power for when recoding next, from the recoding condition onto the optical disk just before interruption thereof, and thereby starting the recording, with the recording power determined from that just after said interruption thereof, wherein an adjustment is made on a tilt angle of an optical pickup when the recording power, which is determined when interrupting the recording operation, exceeds a predetermined threshold value, and the recording is started just after said interruption, with the recording power onto the optical disk just before it is interrupted. Further, by detecting the recording power, again, by reproducing an end portion just before the interruption, or by reducing the recording power determined, the recording is started just after that interruption thereof, with the said reduced recording power.
An optical disk apparatus, comprising:
A method for compensating recording power, in an optical disk apparatus for recording data by irradiating a laser beam upon an information recording surface of an optical disk, which is driven rotationally, and reproducing data recorded by detecting a signal from a reflected light, as well as, while interrupting said recording operation when a predetermined condition is satisfied in continuous recording operation, the recording power is determined, for when conducting recording next, from a recording condition just before said interruption, thereby starting the recording with said recording power determined, just after said interruption thereof, comprising the following steps of:
