Abstract
A magnetic disc cartridge loading and unloading mechanism comprises a shutter opening mechanism which applies no pushing force on a magnetic disc cartridge in a cartridge ejecting direction when the shutter opening mechanism is in an operating state where a shutter of the magnetic disc cartridge is opened. The magnetic disc cartridge loading and unloading mechanism is also provided with a pushing mechanism which pushes the magnetic disc cartridge slightly in the cartridge ejecting direction after sufficient gaps are formed between the shutter and magnetic heads when a holder which holds the magnetic disc cartridge rises to a predetermined height position during a cartridge unloading operation.
