Abstract
A control circuit for a helical scan playback, in which a rotary head is moved transversely by a varying amount. The transverse movement can be either a multi-valued tracking position error correction signal or a saw-tooth waveform, effective during a location data strip, for compensating for the fast movement of the tape during a scan operation.
