Paper Abstract

We manufactured a high-frequency wobbled groove disk, and examined reading/writing a magneto-optical signal by using a clock generated from the wobbled groove. We also measured clock jitter and bit error rate. The results of this were clock jitter of under 2.5 ns, and a bit error rate almost equal to that of a self-clock. This wobbled groove clock method is therefore effective for higher density recording.
