Abstract
A record disk cartridge (34) is disclosed for use in a disk drive unit wherein the cartridge has a compartment containing a record disk (10) therein. The cartridge (34) has aperture means (42) (44) for insertion therethrough of a transducer head of the disk drive unit and through which the record disk can be engaged for rotation. A shutter mechanism (46) (48) associated with the aperture means is movable between an aperture-closed position at least partially closing the aperture means, and an aperture-opened position opening the aperture means. The shutter mechanism is biased by a spring (52) toward its aperture-closed position. An abutment member (54) of the disk drive unit enters into the cartridge to a position within the outer circumference of the record disk when the cartridge is moved to its recording position. The abutment member engages surface means (56) (58) (59) (61) on a shutter blade (48) of the shutter mechanism to move the shutter mechanism from its aperture-closed position to its aperture-opened position as the cartridge is moved to its recording position. The tensioned spring (52) of the shutter mechanism holds the shutter mechanism in its aperture-opened position and the cartridge in its recording position.
