ABSTRACT:
A magnetic recording/reproducing apparatus for recording onto or reproducing from a magnetic tape housed in a cassette by using a rotary magnetic head having a tape withdrawal arrangement for winding a portion of the tape between the two reels in the cassette around the rotary magnetic head by a predetermined angle. A tape drive feed the magnetic tape at a constant speed, with a reel drive being provided for driving either one of the two reels so as to take up the magnetic tape in the reel driven by the reel drive, and with brake arrangement for braking the rotation of the reels. A ring-shaped cam operating member is provided in the outer peripheral surface or the inner peripheral surface thereof with cam surfaces each for effecting the operation of the respective elements in response to the mode of operation of the magnetic recording/reproducing apparatus. The selective operation is specifically determined by the rotational position of the ring-shaped cam operating member, and the rotational position is varied in response to the mode of operation. A detector is provided for detecting the rotational positions in the ring-shaped cam operating member.
