A process for assembling a disk cartridge is disclosed. The process includes the steps of snapping a top shell half of the disk cartridge over a bottom shell half of the disk cartridge; adjusting the shell halves until the shell halves are in abutment contact with each other at a weld site; and directing an energy beam at the weld site until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. The process is repeated for each of a plurality of weld sites located on the perimeter of the disk cartridge. A process for assembling a disk cartridge is disclosed in which an energy beam is split into a plurality of split energy beams. The plurality of split energy beams are focused on a plurality of weld sites until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. A disk cartridge prepared by either of the above described processes is also disclosed.
摘要:
A disk cartridge has a rotary inner shell, or shutter, to permit access to a data-storage medium disposed within the shell. A driving-access opening is located in a bottom surface of the cartridge's outer shell to allow a drive mechanism to rotate the storage medium. A portion of the inner shell projects into the driving-access opening to aid in the rotational alignment of the shell. The outer shell has a wedge-shaped disk-access opening. The inner shell rotates over a predefined arc to expose the data storage medium via the disk-access opening. A liner is disposed between the inner and outer shells to reduce sliding friction between the shells.

A disk cassette for use in a disk drive. The cassette employs a detent mechanism to resistively retain a shutter in a closed position. This shutter is opened by applying a force greater than the resistive force of the detent mechanism. The detent mechanism eliminates the need for a spring bias to retain the shutter in a closed position.

A disk cartridge, for use in a disk drive, has a shutter for opening and closing over a disk access opening. A compression spring provides a force to bias the shutter to a closed position. The spring is coupled at one end to the shutter and follows an arcuate path substantially concentric with the disk within the cartridge.

A system is for mounting a removable media disk cartridge in a disk drive without translating the cartridge or spindle motor in a Z-axis relative to each other The system comprises a spindle in the drive having a substantially planar top surface with an annular groove disposed and an datum ring disposed thereon. The annular groove accepts an inner ring surface of a media disk hub. The disk cartridge has a hub with an inner ring that engages the annular groove in the spindle. Additionally the hub has an outer peripheral edge that has an angled surface. During disengagement of the hub from the spindle, the hub is tilted when the cartridge shell engages the outer peripheral edge. The datum ring acts as a fulcrum while the inner ring is tilted out of the annular groove.

A system for inserting and ejecting a cartridge from a removable media disk drive is disclosed. The system works by pushing the cartridge into the drive until a stop is reached. Thereafter, when the pushing is ceased, the cartridge is locked into position in the disk drive. To eject the cartridge, the cartridge is again pushed into the drive until a second stop is reached. Thereafter, the cartridge is ejected form the drive.

摘要:
A disk cartridge has a hub with an inner ring that engages an annular groove in a drive motor. The hub can be constructed of either one piece or two pieces of joined sheet metal. In either embodiment, the hub has an outer peripheral edge that has an angled surface. The hub can be attached to the medium via adhesive or mechanically by way of a retainer.

A data-storage cartridge has a rotary inner shell, or shutter, to selectively permit access to a data-storage disk disposed within the shell. The shutter is equipped with a wedge-shaped opening through which access to the data-storage disk is attained. A fabric liner is affixed to the inner surface of the shutter to isolate the disk from direct contact with the shutter. The ends of the liner extend beyond, i.e., overhang, the edges of the shutter which form the disk-access opening, thereby preventing direct contact between the data-storage disk and the edges.
