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

Abstract

PURPOSE: To prevent the deterioration of the regenerated picture quality by counting the number of the pulses of the rotary cycles of the rotary magnetic head to obtain the tracking correction voltage in synchronization with the cycle of the control pulse and also changing the counting phase in accordance with the running velocity of the magnetic tape.
CONSTITUTION: Rotary magnetic heads 11A and 11B are supported by head servo circuit 40 consisting of the electricity-machine conversion elements, and magnetic tape 1 is run with a fixed velocity on the rotary circumferences of heads 11A and 11B to regenerate the video signal to be supplied to regeneration signal system 10. At the same time, the output of frequency generator 34 is counted to generate the pulse of the frequency proportional to the running velocity of tape 1 through the track of tape 1. Then the signal relating to the cycle of the control pulse counted based on the rotary cycles of heads 11A and 11B is drawn out via head servo system 40 to be then supplied to tracking correction circuits 100 and 200 via normal/ special change-over switch 13. And the phase of the counted pulse is changed according to the running speed of tape 1 to carry out the regeneration of the picture.
