Abstract

PURPOSE:To carry out tracking control without using control pulse, by comparing the phase of rotation-detecting pulse for the rotary head with the phase of the vertical synchronizing signal in the reproduced video signal, and by controlling the time of the phase difference in these phases so as to be constant.
