Abstract

PURPOSE:To make unnecessary the control pulses, which is operative to ensure it that a head goes along a track during the reproducing operation, by providing on the track of a recording medium a periodic signal generator, which has its running direction shifted, to detect the signals which are indicative of a preset time shift.
