发明名称 Magnetic recording and/or reproducing apparatus having a rotary head tracking control device
摘要 A magnetic recording and/or reproducing apparatus has a tracking control device for performing tracking control by varying the height position of a rotary head which rotates to record and/or reproduce signals in an oblique track on a magnetic tape, according to a control signal applied to the tracking control device. The magnetic recording and/or reproducing apparatus comprises a detecting device for detecting the height position of the rotary head at a predetermined position within an angular range of the rotary head, where the rotary head does not make contact with the magnetic tape, and a control signal forming circuit for forming a control signal according to the output of the detecting device and supplying the control signal to the tracking control device to control the height position of the rotary head so that the height position becomes constant.
