Abstract

PURPOSE: To correct a shift in sampling position due to elapse variation, temperature variation, etc., by obtaining a fixed error voltage whenever the vertial synchronizing signal of an input video signal and pulses PG bear fixed relation.
CONSTITUTION: A drum servo circuit is provided which obtains error voltage e1 by applying vertical synchronizing signal V of input video signal S0 and pulse signal PG from head drum 3 to a 1st phase comparator circuit, for example, composed of trapezoidal wave generating circuit 32 and sample holding circuit 33. Then, a 2nd phase comparator circuit composed of FF31, counter 28, etc., for example, is provided which detects specific phase relation between vertical synchronizing signal V and pulse signal PG, and characteristics of a drum servo circuit is corrected by its output. Therefore, a shift in sampling position due to elapse variation and temperature characteristics is corrected to obtain an error voltage of fixed magnitude whenever vertical synchronizing signal V and pulses PG bear fixed relation.
