Abstract

PURPOSE: To control the stop position of a tape by using horizontal synchronous pulses in a reproduced signal still reproduction of VTR on rotary double-head system.
CONSTITUTION: Recording tracks A2∼A4, and B2∼B4 are given an azimuth and recorded by two different heads. In still reproduction, head surfaces scan from the initial point of track A to the terminal point of adjacent track B and two heads reproduce signals at parts shown by dotted lines and slanting lines. When heads and recording tracks bear correct position relation, horizontal synchronous pulses Ph detected by two heads shown by D and E can be obtained and in vertical blanking intervals of alternate frames, jumping of 0.5H is caused. If heads and tapes are not positioned correctly, pulses shown by B and C are obtained the jumping of 0,5H is disordered. For the purpose, the disorder is detected and the tape position is controlled to obtain the above-mentioned correct position relation.
