The Y/C and synchronous division processing part(12) receives played data through the head output switch part(10) and divides it into color/luminance signal(Y/C) and horizontal/vertical synchronous signal and outputs them. The micro computer(13) receives horizontal/vertical synchronous signal and PG mono multi signal of the Y/C and synchronous division processing part(12) and outputs various controlling signals. The drum motor(14) detects location of a head maintaining constant angle with the head when a motor rotates and outputs PG signal. The PG mono multi(15) receives PG signal from the drum motor(14) and corrects mechanical error of the PG signal. The line error compensating part(100) compares vertical synchronous signal with standard window signal generated by the micro computer(13) at a switching point of head switching signal and outputs error compensating signal according to the result of comparison.
