ABSTRACT:
A head drum servo control method for high speed searches in a magnetic tape regenerating apparatus and a device thereof are disclosed, the device comprising a head drum revolution speed voltage supplying means which consists of various specific means, the method comprising; a first step in which a constant relative speed voltage for the head relative to the tape and cosine and sine values of a constant inclination angle are set in advance; and a second step in which a head revolution speed voltage value is calculated in accordance with the variation of a tape running speed based on a specific formula. If the device and method of the present invention are adopted, the revolution velocity of the head drum can be rapidly started up during the transition from the normal regeneration to a high speed search.
