Abstract
In a rotary head type digital audio signal reproducing apparatus such as an R-DAT or the like, disturbances in the operation of a capstan servo circuit due to erroneous detection of sync signals or interference caused by incompletely erased pilot signals are prevented. Differences between the levels of crosstalk of pilot signals from the two tracks adjacent the on-track being scanned are checked to see if they have a predetermined relationship with the level of the signal being currently supplied to the capstan servo. If this predetermined relationship is not satisfied, supply of the signal which represents the amount of track deviation to the capstan servo is inhibited.
