摘要:
A disk cartridge for use in a disk drive. The disk cartridge 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 plastic disc for storing digital information is disclosed. The disc comprises a plastic platter that is integrally formed concentrically around a metal portion. The disc may have an inner plastic portion located on an inside rim of the metal portion. Preferably, the metal portion has a flange on its rim surface to enhance bonding with the plastic. In another embodiment, the disc may be formed entirely of plastic, and include a clip for attaching the disk to a spindle motor. A disc drive that cooperates with the disc devices, and a method of forming discs are also disclosed.

A frame plate (19) is mounted to the inside of a case (4) of a magnetic recording device (1), and a disk drive motor and a head body (5) are mounted to the frame plate (19). A member (88) for preventing the deformation of the case is provided between the case (4) and the frame plate (19). The member (88) is placed in a cartridge passing area by the action of a spring in the absence of the cartridge (2), but the member (88) is pressed with the front end of the cartridge (2) when the cartridge (2) is moved forward, the member (88) is forced to retreat to the outside of the cartridge passing area.

A data recording cartridge that includes a shell that protects a data recording medium from damage and from particulate contamination is disclosed. When the cartridge is in a closed position, the top shell and bottom shell form a seal to exclude particulate matter from the data recording medium. Because the seal encloses the perimeter of the data recording medium, both internally generated and external particulates do not contaminate the data recording medium. A drive for opening and operating the cartridge is also disclosed. Another aspect of the present invention includes a hub having an enlarged center hollow, and a spindle motor having a top protrusion that fits into the enlarged center hollow. A spindle motor top bearing juts into the underside of a cavity created by the protrusion, thereby more efficiently using vertical space.

A system for inserting and ejecting a cartridge from a removable media disk drive is disclosed (50). The system works by pushing the cartridge into the drive until a stop is reached. Thereafter, when the pushing is ceased, the cartridge (10) 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 from the drive.

A disk drive comprises a magneto-resistive read head (20) and an inductive write head (22) for use with removable hard disk cartridges. A four-bust embedded servo is written and read to guide the servo-positioning of the magneto-resistive read head over data tracks (24) recorded on the removable hard disk (12).
摘要:
A carriage assembly for a disk drive actuator comprises a load beam having a tab extending distally from its distal end, a gimbal having a proximal end connected to the distal end of said load beam, and having a flexure upon which a read/write head is the load attached. The gimbal had a restraining member at its distal end, through which the tab of the load beam extends. The restraining member contacts the tab when the carriage assembly undergoes shock, to prevent excessive movement of the gimbal.
摘要:
The magnetic recording unit is enclosed with a case body (15, 16). A cartridge insertion slot (18) for inserting a cartridge housing a disk, which is a recording medium, is formed at the rear end of the case body (15, 16), and a frame plate (19) is disposed inside the case body. A first concave section and a second concave section are formed on this frame plate (19) by drawing processing, a disk drive motor (5) is mounted using the first concave section, and a head drive motor (16) for driving the record/playback head body (17) for the disk is mounted using the second concave section.
摘要:
An apparatus for retaining a cartridge in a removable media disk drive during drive operation is disclosed. The apparatus has a protuberance at a distal end of a flexible arm. When a cartridge is pushed into the drive, it engages the protuberance and flexes it along the edge of the cartridge. The protuberance flexes back when it engages a cut-out in the side of the cartridge. An opening in a side wall of the disk drive chassis allows the flexible arm to flex out when the cartridge engages it. The flexible arm is attached to a sliding lever. As the cartridge is inserted further into the drive, the flexible arm moves past the opening and thereby locks the cartridge into the drive.
摘要:
A disk hub for a removable cartridge is disclosed that has an enlarged center hollow, and a spindle motor is also disclosed that has a top protrusion that fits into the enlarged center hollow. The center hollow and protrusion have diameters at least as large as the outside diameter of a spindle motor top bearing. While the spindle motor is engaged to the hub, the top bearing projects into the center hollow, thereby efficiently using vertical space.
