Claims

[Scope of utility model registration request]

A clamp member for clamping a magnetic disk on the turntable is provided at a position facing the rotationally driven turntable, and the clamp member is held by a clamp arm that moves toward and away from the turntable, and The clamp arm is connected to a drive lever, and a magnetic recording/reproducing device is provided with an operation cam that presses the drive lever to move the clamp arm in the clamping direction. a pad holder that can approach and separate from the pad holder; an elastic member that comes into contact with the pad holder and restricts its movement toward the magnetic disk; and an engagement member that moves the pad holder with the drive lever against the elastic force of the elastic member. A disk pressing mechanism for a magnetic recording and reproducing apparatus, characterized in that the elastic member temporarily interrupts the movement of the pad holder toward the magnetic disk.
