Abstract
A digital signal reproducing apparatus which reproduces digital PCM audio signals recorded on a recording medium in the form of single helical tracks. The signals recorded on the recording medium are reproduced by a rotary head. In order to prevent the erroneous detection of an ATF (Automatic Track Finding) signal, block addresses recorded in subcodes and PCM areas are read into a system counter which is used for forming a window for detecting ATF synch signals, and then the count value of the system counter is compensated for.
