Abstract
We have investigated a clock generated from a wobbled groove for higher density magneto-optical disk. Neither the readout signal nor the recording signal needs to include a clock element, because a clock derived from the wobbled groove is used for recording and readout. Therefore this clock does not depend on the quality of the readout signal. For this reason, a clock generated from the wobbled groove is effective for higher density recording.
