ABSTRACT:
A control circuit for a recording and reproducing apparatus. The circuit includes a single magnetic head for recording and reproducing signals corresponding to data on a recording medium, a recording circuit for supplying a recording signal to be recorded to the magnetic head, a reproducing circuit for amplifying a reproduced signal detected from the recording medium by the magnetic head; and a switch for selectively shifting the apparatus between a recording phase wherein the recording circuit is activated, and a reproducing phase wherein the reproducing circuit is activated, wherein the reproducing circuit includes capacitors for storing an electric charge during operation of the apparatus, and buffers for maintaining the charge stored by the capacitors at a substantially constant level when the switch shifts between the recording phase and the reproducing phase.
