摘要： A read/write head for use in a disk drive having chamfered surfaces reducing possible damage to the head assembly and/or media during loading and unloading of heads form media surface. In an inadvertent collision between the media and head assembly, the media may become displaced, possibly damaging the head suspension assembly or critical electrical connections between the head assembly and media drive. Similarly, such a collision may impart irreversible physical damage to the recording medium, making the data on the medium unrecoverable. The present invention comprises chamfered surface, preferably formed into the head, which reduces the likelihood of damage caused to the head assembly or media in the event of an inadvertent collision. These chamfered surfaces deflect the media to its proper position such that damage is minimized during collision.

摘要： A disk drive for writing and reading data to and from a disk contained in a cartridge which is inserted through an opening into the disk drive comprises a motor ring rotatably mounted in the disk drive and a spindle motor for rotating the disk. The spindle motor is mounted in the motor ring such that rotation of the motor ring moves the spindle motor into and out of engagement with the hub of the disk cartridge. A position transducer provides an output signal indicative of the rotational position of the motor ring. A load/eject motor controls the rotation of the motor ring in response to the output signal from the position transducer.

摘要： A cartridge for a magnetic disk drive has a clamping mechanism which is actuated as the door to the cartridge is closed when the cartridge is removed from the drive. The door covers the opening through which the cartridge is accessed by read/write heads. When the cartridge is removed from the drive, the mechanism of the present invention clamps the recording disk against the cartridge shell to prevent rattle, which might otherwise damage the recording disk.

摘要： A seal is coupled to a movable member in a disk drive for sealing an opening in a chassis over which the movable member passes. The seal comprises a first layer of foam attached to the movable member, and a second layer of low-friction plastic attached to the layer of foam. The foam layer presses the plastic layer against the chassis to seal the opening as the plastic layer slides over a surface of the chassis.

摘要： A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door which opens along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

摘要： A disk cartridge comprises a flexible disk rotatably mounted in an outer casing. The outer casing comprises upper and lower shells that mate to form the casing. Each of the upper and lower shells has an inner surface disposed in facing relation to a respective surface of the disk. A number of radially extending stabilizers are arranged on the inner surfaces of the upper and lower shells so as to induce a predetermined standing wave pattern in the flexible disk as the disk spins at high speeds, and to maintain the standing wave patter as the recording heads of a disk drive move radially over the surface of the disk. Additionally, at least one pair of opposing projections are disposed on the inner surfaces of the upper and lower shells near a head access opening in the front peripheral edge of the cartridge. The opposing projections have a spacing, S, and serve to center the edge of the disk during head loading operations.

摘要： A crush resistant cartridge case comprises a case shell having left and right halves. Each halve of the case shell contains a rigid insert having a flat portion with a rib extending substantially around the perimeter of the flat portion. The rigid inserts in the left and right halves of the case shell come together when the case shell is closed and provide resistance against crushing.

摘要： A head loading mechanism for a removable cartridge disk drive comprises a support base fixedly mounted in the drive, and a moveable member movably attached to the support base via a pair of elongate flexures. The moveable member has a ramped surface adapted to engage a suspension arm at the distal end of an actuator. A read/write head is mounted on the suspension arm. The moveable member moves upon the flexures in tandem with the actuator as it moves toward and away from the edge of a disk inserted in the drive. The moveable member carries the suspension arm of the actuator to the edge of the disk, at which point the suspension arm can ride up and down the ramped surface of the moveable member in order to load the read/write head onto the surface of the disk and then subsequently to unload the read/write head from the disk.
