Abstract

PURPOSE: To facilitate the selection, adjustment and others for the component parts by securing the coincidence between the signal obtained by delaying a fixed time both the vertical and horizontal synchronous signals isolated from the input video signals and the 1st and 2nd velocity detection signals provided to the driving motor of the rotary head.
CONSTITUTION: The rotary phase of motor 9 is controlled via the control system so that the coincidence may be secured between signal VD' which is obtained by giving the delay of a fixed time to the vertical synchronous signal isolated from the input video signals and the PG signal obtained from the 1st velocity detectin means, such as pulse generator 11, provided to driving motor 9 of the rotary head, along with the coincidence between the horizontal sycnhronous signal isolated from the video signals, clock signal CK synchronized with the delayed signal above mentioned and the PG signal obtained from the 2nd velocity detection means, such as frequency generator 10, respectively. As a result, the adjustment can be facilitated without using the high-accuracy component parts.
