Title: Video signal reproducing device
Inventor: FUJIMOTO MIKIHIRO
IPC: G11B15/467
Filed: 1989-08-23
Abstract: PURPOSE:To subtly and stably perform adjustment by providing a means for adjusting the sampling timing of a sampling means and controlling a relative position between a recording medium and a rotating head in accordance with a sampled error signal. CONSTITUTION:When a mode becomes a high speed reproducing mode by an operation part 2, switches SW2 and SW1 are turned on and off and the reproducing signals of heads HA and HB are alternately fetched from switches SW4 and SW5. Meanwhile, the reversal signal of an HSWP is supplied to a four- frequency generation circuit 9 and four kinds of reference pilot signals are circularly generated. At such a time, a capstan driving circuit 14 is controlled so that the frequency of a capstan rotation detecting signal may be several times as many as the frequency at the time of recording and a tape T travels at a high speed, so that the frequency is separated by a BPF 7. Thus, a tracking error ATF signal from an ATF circuit 8 becomes in a sine wave state. When the level of the ATF signal is near a zero level, a capstan speed is increased and when the level of the ATF signal is small, the capstan speed is decreased. Thus, the position of a noise bar on a screen is adjusted.
