ABSTRACT:
A rotary scanning-type magnetic recording and reproduction apparatus comprises a plurality of magnetic heads installed on a rotary drum, and being in contact with a magnetic tape running on the peripheral surface of the rotary drum, for recording the information signal onto the magnetic tape and/or reproducing the information signal from the magnetic tape, a plurality of recording circuits connected to the magnetic heads respectively, for processing the information signal to be recorded on the magnetic tape transferred from outside the rotary drum and output it to the magnetic head, a rotary transformer for transferring the information signal sent from outside the rotary drum to the recording circuits, and a control circuit for sequentially selectively bringing the recording circuits into an active state according to the rotational position of the rotary drum, and bringing the recording circuits into an active state only during a period of time when the information signal is detected.
