Claims

[Claims for Utility Model Registration] In a magnetic recording and reproducing device for recording and reproducing various data on a magnetic disk rotatably housed in a disk cassette having a shutter biased by an elastic member so as to cover a head access window, an operating position for holding the disk cassette in a state where recording and reproduction are performed on the magnetic disk;
a cassette holder supported by a frame so as to be movable to an inactive position where the disk cassette can be inserted and ejected; and a slide provided on the cassette holder and inclined at a predetermined angle with respect to the insertion direction of the disk cassette. When the disc cassette is inserted into the cassette holder, the shutter comes into contact with the sliding contact surface while entering the notch formed at the insertion end of the disc cassette, and the shutter comes into contact with the sliding contact surface. an opening/closing member for opening the head access window by moving the head access window in a direction perpendicular to the insertion direction against the elastic force of the elastic member.
