Abstract: A tool for detaching a trailing end portion of a filmstrip from at least one hook atop a ramp on a film spool inside a film cartridge. This detachment occurs when the tool is inserted inwardly through a film ingress/egress slot in the cartridge. The tool includes a flexible element having a leading first portion followed by a wider second portion each configured to be successively inserted inwardly through the slot of the cartridge beneath a film section in the slot such that when the wider second portion is forced to slide up the ramp on the spool the leading first portion will push the trailing end portion of the filmstrip off the hook atop the ramp.

Abstract: 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.

Abstract: A disk drive spindle and spindle motor assembly is mounted on a support platform which is translated reciprocally toward and away from a stationary disk cartridge by a pair of rotationally driven cranks positioned along opposite sides of the platform. The cranks are coupled to the platform by eccentrically mounted support rods loosely captured in the span between dual sets of parallel, compliant leaf springs attached to side edges of the platform. The rotational cranks are provided with a degree of overtravel to forcefully urge the platform, when in the operational position, against precision stops formed on the underside of a mount plate located between the platform and disk cartridge. The spatial relationship of a disk engaging surface on the drive spindle relative to the precision stops is such as to precisely position the rotating disk in parallel with the tracking axis of the read/write head of the system.

Abstract: 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.

Abstract: 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.

Abstract: A write protect mechanism is disclosed for a cartridge of the type having top and bottom plates and an information recording medium interposed therebetween. The write protect mechanism comprises a button visible through an aperture in one of the plates and slideably moveable in the aperture between a write protect position and a write enabled position. In the write protect position, an interfacing recording device is actuated to prevent recording so that information previously recorded on the disk will not be inadvertently erased. In the write enabled position, the recording device is actuated to record information on the disk. The button further has a flag adapted to extend into a gap in a rear peripheral wall joining the top and bottom plates to visibly indicate that the button is in the write protect position and that information can not be recorded on the medium. When the flag is retracted, this visibly indicates that recording, if not prevented, could inadvertently erase previously recorded information.

Abstract: A disk cartridge comprises top and bottom opposed spaced-apart plates defining a compartment in which an information recording disk is rotatable. A front peripheral wall joins the top and bottom plates with an aperture in the front peripheral wall communicating with the compartment. The disk cartridge is provided with a brake mechanism that latches the disk axially and radially in an operative plane until the cartridge is inserted fully into a drive mechanism. The brake mechanism also functions to protect the disk against damage, abrasion, cracking and the like, by eliminating annoying rattling when the cartridge is jostled during transporting or in handling. The disk brake mechanism comprises a unitary spring-biased pivotally mounted brake member on one side of the disk center for engaging the periphery of the disk and clamping the disk between the brake member and a pair of angularly spaced nooks located on the opposite side of the disk center.

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.
