Appl. No.:

7/287806

Inventors:

Ronald A. Crain - San Jose CA
Harney James D. - Mountainview CA

Assignee:

Literal Corporation - Colorado Springs CO

International Classification:

G11B 3302
G11B 1704

US Classification:

369 772

Abstract:

Cartridge positioning apparatus for loading and unloading the disk cartridge of an information storage disk drive system employs a dual function, motor-actuated, laterally moving linear drive mechanism to drive a plurality of drive plates located in an interstitial space between a cartridge receiving guide means and a central mount plate by means of a drive tab extending up through the mount plate. The tab engages a camming plate which operates against the central portion of a pivoted sector gear to convert the lateral tab drive motion into amplified longitudinal motion parallel with the direction that the disk cartridge is inserted and removed. The camming plate includes an idling provision to hold the sector gear stationary while the motor-performs other load functions. The sector gear drives a longitudinal drive mechanism which carries one or more members adapted to contact the disk cartridge for loading or unloading the cartridge depending on the direction of movement of the motor-actuated drive tab.

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.
