摘要： An apparatus for reproducing an information signal from a recording medium on which many tracks are formed, by periodically tracing the recording medium with a recording head. The position of the reproducing head relative to the recording medium is controlled on the basis of a tracking error signal which is obtained from the signals reproduced by the reproducing head. The track pitch is determined by a discrimination of a binary signal which is formed on the basis of a determination of whether the tracking signal is within a predetermined range.
