Apparatus for receiving a removable disk cartridge

A disk drive apparatus of the type that receives a removable disk cartridge, comprising:

• a slide plate slidably mounted on a chassis of said disk drive apparatus, said slide plate engaging said removable disk cartridge and moving in tandem therewith from a first position to a second position upon insertion of the disk cartridge into the disk drive apparatus,
• said slide plate having at least one flexure that has a projection formed thereon, said at least one flexure moving from a position away from said cartridge, to a position adjacent said cartridge as the cartridge and slide plate move in tandem upon insertion of the disk cartridge into the disk drive apparatus, the projection on said at least one flexure moving into engagement with a reference hole on said cartridge as said slide plate reaches said second position thereof;
• a first spring biasing said slide plate in a direction toward said first position and opposite the direction of insertion of said removable disk cartridge,
• wherein as said slide plate moves in tandem with the disk cartridge toward said second position, each of said at least one flexure travels along a respective inclined cam slot provided in said chassis within said disk drive apparatus to drive each respective one of said projections through a cutout in said chassis and into engagement with respective reference holes on the cartridge.
