た磁気ディスク記録再生装置。[Scope of Claim for Utility Model Registration] A cartridge for rotatably storing a magnetic disk has a cartridge window on one side for recording and reproducing information on the magnetic disk, and a shutter window corresponding to the cartridge window. When the shutter is slidably attached to the cartridge and the cartridge is installed in a magnetic disk recording and reproducing device, the shutter that closes the cartridge window slides outside the magnetic disk recording and reproducing device, and the shutter window and the cartridge close together. A magnetic disk recording and reproducing device that records and reproduces information by bringing a disk into contact with a magnetic head for recording and reproducing at once through the cartridge window, and is installed in the magnetic disk recording and reproducing device. An entry prevention member is provided at at least one of the corresponding corners of the leading end of the cartridge in the insertion direction, and the right and left corners of the leading end of the cartridge in the insertion direction are formed into an asymmetrical shape, so that when the cartridge is inserted normally. The cartridge can be inserted up to a predetermined position, and when the cartridge is inserted upside down, the front corner of the cartridge in the insertion direction comes into contact with the entry prevention member and is prevented from entering just before the predetermined position is reached. What is claimed is: 1. A magnetic disk recording and reproducing device equipped with means for preventing reverse insertion of a cartridge.
