Abstract
A magnetic disk drive has a mechanism for loading and holding a disk cartridge inserted with a correct orientation at a predetermined position, and for preventing a disk from being inserted with a wrong orientation from being loaded at the predetermined position. The mechanism needs so few members that the magnetic disk drive can be made smaller and thinner. Particularly the mechanism is effective for a magnetic disk drive including a disk cartridge and a driving device. The disk cartridge is an apparatus having at least a disk and a head in a sealed case, but it has no current supply source to drive them and has no controller to control the disk and head. The driving device has the current supply source and/or the controller. The disk cartridge may be considered as being an easily exchangeable hard disk.
