Abstract: PROBLEM TO BE SOLVED: To attain the automatic adjustment and to omit the analog adjustment by controlling the revolution of a rotary drum according to the controlled variable stored in a storage means after the prescribed adjustment and deciding the timing to produce a head switching signal. SOLUTION: A storage 33 stores previously a controlled variable equivalent to 400 μsec approximate to 6.5 H (412.75 μsec), for example, as the initial value that functions to set a space at about 6.5 H (horizontal scanning period) between a head switching signal and a vertical polarizing signal when an operation is started in an adjustment mode. A microcomputer 31 reads the controlled variable equivalent to the initial value out of the storage 33 and converts the controlled variable into the servo control target value to output it to a servo system 32. The system 32 performs the servo control of the rotational frequency of a drum motor 8a and the tape running so as to secure the said target value.  As a result, the timing of the head switching signal is controlled and accordingly the space is automatically and accurately adjusted at 6.5 H between the head switching signal and the vertical synchronizing signal of a video signal.
