ABSTRACT:
A magnetic disk cartridge has a cassette shell provided on its outer surface with at least two guide grooves located symmetrically on its outer surface to extend parallel to its direction of insertion into a magnetic disk cartridge drive device. The floors of the guide grooves are formed with teeth for enabling the magnetic disk cartridge to be automatically loaded and unloaded to and from a magnetic disk cartridge drive device by meshing of the teeth with an autoloading drive gear section provided in the magnetic disk cartridge drive device. The structure improves the dimensional precision of the cassette shell and provides the magnetic disk cartridge with autoloading capability.
