Abstract

PURPOSE:To keep tracking state in excellent, by using a signal obtained from a preamble and a postamble to a PCM data, in the reproduction of an overlap section where no tracking control pilot signal is obtained. CONSTITUTION:In a VTR adopting an overlap system, a digitized signal based on an audio signal or the like, e.g., PCM signal Sa is recorded to the prolonged part of recording tracks (T1, T2, T3 and T4), i.e., an overlap section rL, and this is reproduced with a video signal Sv. In the reproduction of the overlap section rL in which a tracking control pilot signal (f1, f2, f3 and f4) as the crosstalk component is not obtined, control is made with a tracking signal which is obtained from the comparison between both the signals obtained from the scanning of the overlap part of one preceding recording track with a preamble signal Pr and a postamble signal Ps for a PCM data in a PCM signal and obtained from the crosstalk component.
