    • In an information disk drive system, a pivoted shutter opening lever is positioned in a cartridge receiving guide in the same plane as the disk in the cartridge. The lever is mounted on a movable pivot with a shutter engaging member positioned to begin opening the cartridge shutter to expose a segment of disk recording tracks only after the segment is inside the disk drive and to complete opening of the shutter at an intermediate stage of cartridge insertion to allow nesting of disk access components within the disk access opening in the cartridge prior to the cartridge reaching its final operating position. Interference between the opening lever and the fully opened shutter during final travel of the cartridge is avoided by a mechanism which moves the lever pivot by a sufficient amount to allow the shutter engaging member to translate in a straight line parallel to the insertion path of the cartridge during final insertion motion of the cartridge. Two embodiments of the pivot moving mechanism are shown.

    • A cartridge comprises a rigid peripheral wall sandwiched between a pair of similarly rigid major surfaces, to form a compartment containing a disk arranged for rotation about a central axis. The cartridge obviates the need to have relative axial movement between the disk and a record/playback transducer head as the cartridge is loaded into a drive mechanism. To that end, a brake mechanism latches the disk axially, as well as radially, in its operative plane as the cartridge is loaded; additionally, the cartridge exposes the disk sufficiently to provide interference-free access to it by the transducer head. For that purpose, at least one of the major surfaces has a head-access opening extending to the peripheral wall, which, in turn, defines a relatively narrow bridge-like member, comparable in width to the operative plane of the disk, extending laterally, in the disk plane, from one side to the other side of the head-access opening. The bridge-like member, in addition to simplifying loading movement, maintains cartridge rigidity across the "throat" of the head-access opening.

    • 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.

    • Apparatus for centering and clamping a disk on a spindle-drive is disclosed. A bistable magnetic clamp normally held in an axially offset position from the plane of the disk is preferentially drawn to a coupler washer on the spindle-drive when the spindle-drive and clamping device are relatively moved toward each other after the disk is inserted into the drive. To accommodate significant initial misalignment of the disk, as might typically occur with a cartridge mounted disk, in a very short throw clamping motion, a multi-frustrum centering member is used. The frustrum surface nearest the disk has a gradual slope assuring meshing of the centering member with the central aperture of the disk over a wide range of initial misalignment. Once the disk is coarsely centered, precision centering is achieved during the final clamping stage by the second frustrum surface which is at steep slope relative to the plane of the disk.
