Abstract
A method of automatically pausing an optical pickup in a DVD-RAM disc drive includes driving a DVD-RAM disc; determining whether a tracking error signal is generated during the driving of the DVD-RAM disc; generating a land/groove signal to discern land tracks and groove tracks of the DVD-RAM disc; determining from which track the tracking error signal has been generated in response to the determination that the tracking error signal has been generated; generating a jump signal in response to a state of the land/groove signal varying; and moving the optical pickup back by ½ of a track in response to the jump signal.

A method of automatically pausing an optical pickup in a DVD-RAM disc drive, the method comprising:
- driving a DVD-RAM disc;
- determining whether a tracking error signal is generated during the driving of the DVD-RAM disc;
- generating a land/groove signal to discern land tracks and groove tracks of the DVD-RAM disc;
- determining from which track the tracking error signal has been generated in response to the determination that the tracking error signal has been generated;
- generating a jump signal in response to a state of the land/groove signal varying;
- and
- moving the optical pickup back by ½ of a track in response to the jump signal.
A method of automatically pausing an optical pickup in a rewritable disc drive, the method comprising:
- receiving a land/groove signal;
- discerning between land tracks and groove tracks according to the land/groove signal;
- and
- moving the optical pickup back by ½ of a track;
- wherein the optical pickup is positioned over either the land tracks or the groove tracks in response to the land/groove signal.
A method of automatically pausing an optical pickup in a rewritable disc drive, the method comprising:
- generating a land/groove signal to discern between land tracks and groove tracks of a rewritable disc.
