Abstract
PURPOSE:To improve the S/N ratio of a reproduced signal while managing with only one head amplifier by equipping switch elements in a rotary drum and by controlling it by an erasure signal. CONSTITUTION:During recording, an input signal is applied via a rotary transformer 6. An erasure signal is applied to an erasing head 5 through a rotary transformer 8 and also supplied to an erasure signal detecting circuit 17, and switch elements are placed at recording sides respectively by a signal from switch driving circuit 18. The said recorded signal is applied to a recording head 3. The output of a monitor head 4 is outputted by a rotary transformer 7 via the switch elements and a head amplifier 16 to monitor the recording operation. During reproduction, no erasure signal is applied and the switch elements are at reproduction sides, so that the output of the head 3 is outputted from the rotary transformer 7 via the switch element and head amplifier 16.
