  • Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)

Abstract

PURPOSE: To realize correction for the tracking error by the saw-tooth waveform voltage which starts earlier than the control pulse by the fixed field cycle by running the magnetic tape with a fixed velocity on the rotary circumference surface of the rotary magnetic head to regenerate the video signal.
CONSTITUTION: Rotary magnetic heads 11A and 11B are suported by head servo circuit 40, and magnetic tape 1 is run with a fixed speed to the rotary circumference surfaces of heads 11A and 11B. Thus the video signal is regenerated to be supplied to regeneration system 10. At the same time, rectangular waveform signal SV which inverts every field period is drawn out via servo system 40 including head 43, pulse generation means 46 and 76, phase comparator 45, FF circuit 78 and others. Signal SV is applied to switch circuit 13 of regeneration system 10, and circuit 13 is switched by the reference pulse of oscillator 49 to then change over the output of heads 11A and 11B to be supplied to tracking correction circuit 200. Then the saw- tooth wave, which starts earlier by the fixed field cycle, is generated based on output signal SV of circuit 78 to give correction to the tracking error.
