Abstract
This invention relates to a method and apparatus for reading out a synchronizing signal recorded in a data portion of each of a number of sectors stored in a recording medium such as an optical disc, a write-in-once type magneto-optical disc and so on. Even when detection of a synchronizing a signal has failed, the succeeding re-synchronizing signal can be detected reliably so that, although a first one divided unit portion of data is dropped out, data following the re-synchronizing signal can be read out positively, thus reducing data read error rate.
