Abstract
A disk cartridge comprises top and bottom plates having integral peripheral lips joined together to form a peripheral wall when the top and bottom plates are secured together. The peripheral wall serves to space the lower surface of the top plate from the upper surface of the bottom plate to define a compartment in which an information recording medium, such as a disk is contained for rotatable movement. At least one of the top and bottom plates is provided with an elongate head-access opening through which a transducer head gains operational access to the record tracks of the disk when the cartridge is operatively loaded into a disk drive mechanism. To protect the disk from adverse external effects such as dirt, lint, fingerprints, and the like, the cartridge is provided with a spring-biased generally U-shaped shutter for automatically covering each head-access opening when the cartridge is removed from a disk drive mechanism. The cartridge is provided with a shutter latch mechanism in the form of a resilient spring arm mounted within the cartridge compartment and having a free end portion adapted to engage the inwardly facing shoulder of a recessed portion of the shutter to latch it in its closed position.
