Referring to FIG. 1 showing a control head position adjusting apparatus according to an embodiment of the present invention, a microscope 1 captures an image of a rotary magnetic head 110 fixed to a drum 11, and an image pickup device 2 captures the image as an electrical signal. And is transferred to the arithmetic unit 3. In addition, the motor 10 that rotates the drum 11
A pulse signal from a pulse generator (not shown) attached to is also transferred to the arithmetic unit 3. Further, the microscope 6 whose position with respect to the microscope 1 is fixed captures the image of the control head 12, and the image pickup device 7 converts the image into an electric signal and transfers it to the arithmetic unit 4. The arithmetic unit 3 compares the position of the rotary magnetic head 110 with the pulse signal from the motor 10 and calculates a time error from a time delay defined as a reference, and the result is sent to the arithmetic unit 4 via the cable 8. Forward. The arithmetic unit 4 converts the time error into an error in the position of the control head 12, and calculates the difference from the position of the control head 2 currently sent from the image sensor 7. Based on the result of this calculation, the adjuster 5 is rotated to rotate the control head mount 13, and the position of the control head 12 is adjusted. The mounting base 13 has an elongated hole for allowing rotation, and is normally fixed to the base 14 with a screw.
