Patent ID: 8284644

Claim:
An optical disc recording method for real-time recording of broadcast digital data in an optical disc having a first recording layer and a second recording layer, the method comprising steps of: when a focus servo is in a locked state, recording digital data in the first recording layer with a laser light set for recording power; during the recording of the digital data, when a recording position for a next recording digital data bridges from the first recording layer to the second recording layer, switching the laser light to a power which is lower than the recording power, and when a focus servo is in an unlocked state, performing an interlayer jump from the first recording layer to the second recording layer with a laser light set for the power which is lower than the recording power, when the interlayer jump from the first recording layer to the second recording layer has failed, performing a servo recovery processing, and when the interlayer jump from the first recording layer to the second recording layer has succeeded, detecting the recording position for digital data recording in the second recording layer, switching the laser light to recording power when the focus servo is in a locked state, and recording digital data in the second recording layer.
