Sync signal detection apparatus.

摘要

There is disclosed a sync signal detection apparatus wherein a sync signal representing the top of recorded data is composed of a plurality of marks each having a pattern different from that of any other mark. The apparatus is equipped with a circuit for sequentially detecting the patterns of the individual marks in a reproduction mode, and a circuit for generating, upon detection of a predetermined number of marks, a sync pulse at the top of the data in accordance with the address pattern of the mark.
