Claims

[Scope of Claim for Utility Model Registration] (1) An information recording/reproducing device having a pick-up that is movable relative to a recording medium installed in the main body of the device, which is movable in a direction substantially perpendicular to the direction of movement of the pick-up. holding means for holding the provided recording medium;
A rotating shaft is provided integrally with the pick-up and moves in the same way as the pick-up, an arm is rotatably supported at one end on the rotating shaft, and the arm is provided opposite to the pick-up with a holding means in between at the other end. and magnetic field applying means, and when the recording medium is not attached to the holding means in a position where information is recorded or reproduced, the holding means is in a position far away from the pickup, and a part of the holding means is When the arm is rotated in a direction in which the magnetic field application means is separated from the holding means by coming into contact with a part of the arm, and the recording medium is attached to the holding means at a position where information is recorded or reproduced, An information recording/reproducing apparatus characterized in that the holding means is located at a position close to a pickup, and the arm is rotated in a direction to bring the magnetic field applying means close to the recording medium. (2) Information according to claim 1, characterized in that the arm is provided with a separating means that comes into contact with the holding means when the recording medium is mounted on the holding means at a position where information is recorded or reproduced. Recording and playback device. (3) The information recording/reproducing apparatus according to claim 1 or 2, wherein the magnetic field applying means is provided on the arm via a bimorph vibrator.
