ABSTRACT:
A synchronizing signal detector for a magnetic recording/reproducing apparatus includes a first comparator for comparing a given synchronizing signal pattern with externally input data in a certain bit unit and outputting the number of the same bits in each of comparison unit, a detecting portion for detecting a maximum value of the outputs of the first comparator, and a signal processor for outputting data corresponding to a position where the maximum value from the detecting portion occurs primarily, as a synchronizing signal. In the synchronizing signal detector for a magnetic recording/reproducing apparatus, since the position where the synchronizing signal is generated is detected by comparing the synchronizing signal pattern with the input data, the synchronizing signal detecting error occurs scarcely, thereby improving reliability of the detected synchronizing signal.
