Claims (1)

[Claims for Utility Model Registration] A magnetic disk cartridge comprising a magnetic head insertion window and a shutter for opening and closing this window,
In a magnetic disk recording/reproducing device in which a cartridge holder supported in a freely insertable and removable manner is moved in parallel in the cartridge thickness direction between a cartridge insertion/extraction position and a recording/reproduction set position, the cartridge is moved in the cartridge ejection direction by biasing elasticity. The cartridge holder is lowered to the recording/reproducing set position by sliding in the cartridge insertion direction, and the cartridge holder is upwardly displaced to the cartridge insertion/extraction position by sliding in the cartridge insertion direction against the biasing elastic force. a locking arm that swings due to biasing elasticity and locks the locking portion of the holder guide to lock the holder guide in the retracted position; an operating lever that is movable and has a push arm that is pushed by the cartridge to release the lock of the locking arm, the push arm has an abutting portion that comes into contact with the cartridge; 1. A magnetic disk recording/reproducing device comprising: a sliding portion that slides to open a magnetic head insertion window.
