Claims

[Scope of Claim for Utility Model Registration] A cartridge for rotatably accommodating a magnetic disc has a cartridge window on one side for recording and reproducing information on the magnetic disc, and a shutter window corresponding to the cartridge window. When the shutter is attached to the cartridge cartridge and the sliding mechanism, and the cartridge is installed in the cartridge mounting section of the magnetic disk recording and reproducing device, the shutter sliding means closes the cartridge window when outside the magnetic disk recording and reproducing device. A magnetic disk recording and reproducing device that records and reproduces information by sliding a shutter that aligns a shutter window and a cartridge window so that the magnetic disk is brought into contact with a magnetic head for recording and reproducing at the cartridge window. The shutter sliding means is a shutter sliding member having a guide surface inclined with respect to the downward direction of the cartridge at a position corresponding to the side end of the shutter when the cartridge is inserted into the cartridge mounting portion. 1. A magnetic disk recording/reproducing device characterized in that the side end of the shutter slides on the guide surface of the shutter opening member when the cartridge is lowered.
