<p>PURPOSE: To record a tracking signal only in the specific position in the longitudinal direction of tracking by using the half of both heads in recording the tracking signal and using the half of both heads even for tracking under reproduction as well. CONSTITUTION: Digital video signals are assumed to be supplied to the input terminals 2 of a recorder and reproducer and are assumed to be supplied through signal synthesizing units 9, 10 to the half parts K1 , K2 of both heads and the electric signals are assumed to be written by the half of the two heads of a track T2 and assumed to be simultaneously recorded in each half in the track 12. The frequency spectra of the video signals are divided or the digital samples in the signals are separated before the signals are supplied to the terminals 2, by which the one of the respective signal components is supplied to the input terminal 11 of a unit 9 and the other signal component to a unit 10 and is supplied to the half K1 of one of the respective heads and the half K2 of the other head.</p> |
