Abstract:
1. An optical disc recording method for recording data in a first recording layer and/or a second recording layer by irradiating one surface of an optical disc with laser light, the method comprising the steps of, when it is judged that addresses at which continuous data is to be randomly recorded are positioned in both the first recording layer and the second recording layer: recording data in the first recording layer with the laser light set for recording power; stopping recording in the first recording layer; switching the laser light to nonrecording power and performing an interlayer jump from the first recording layer to the second recording layer; and when the performing an interlayer jump has not succeeded, performing servo recovery processing; when the performing an interlayer jump has succeeded, detecting a target position for data recording in the second recording layer, switching the laser light to recording power, and resuming a data recording operation.
