る記録再生装置。Chucking a magnetic disk having a spindle and a center core having first and second holes into which a driving pin supported by an elastic member is inserted at a position apart from the spindle so as to rotate together with the spindle. In a recording and reproducing apparatus that performs recording and reproduction, a pin supported by the elastic member is provided between the spindle and the drive pin, and at an initial stage when the drive pin enters the second hole, the When the pin is pushed down by the center core, the driving pin acts to move away from the cam side of the second hole, and when the pin enters the second hole, the driving pin moves toward the cam side. A recording/reproducing device characterized in that the pin is set at a position where the pin is pressed against the pin with a predetermined force.
