摘要： A disk drive includes a cast base 5 which supports the spindle assembly and the actuator assembly, and a cover 11 that is loosely received by the cast base to form the head-disk enclosure. The cover is secured and sealed to the cast base by a malleable metal foil tape 30 that surrounds the enclosure and continuously overlies the interface between cover and base. The tape complies with the surface irregularities and does not creep, to provide permanent shielding and sealing between base and cover. Cable exiting the enclosure is sealed using a piece of double sided adhesive between the cable and the casting, with the malleable foil tape thereover. Thus no significant thickness is added to the enclosure by the tape, which also provides noise and EMC shielding in addition to securing and sealing the cover.

摘要： Deteriorated or aged magnetic recording media exhibiting undesirable properties such as shed, stickiness or squeal are restored to playable condition having no such objectionable properties by heating the media to an elevated temperature and for lengths of time sufficient to restore the media. A typical temperature used is 54°C and a typical effective time is 16 hours. Ambient humidity is suitable. The restored media can be used to transfer data or information to new media. Restored media can also be again heat treated for restoration purposes, if it deteriorates again.

摘要： A disk cartridge (20), operable with a disk drive, includes a generally flat-shaped case enclosing a recording medium (38) disposed on a disk (22) about a central hub (40). The case includes top and bottom walls (30,32) disposed on opposite sides of the disk, the bottom wall (32) having an access opening (54) through which a disk drive is to engage with the hub (40). A foil spring (124) has a generally flared dish shape, and is symmetrically formed and positioned about a central axis of the hub (40). The spring (124) is positioned between the disk (22) and the top wall (30) for urging the disk (22) toward the bottom wall (32) to close the access opening (54) with the hub (40) and to close a spindle receiving aperture (48) in the hub (40) to prevent entry of contaminants during periods of nonuse.

摘要： In a magnetic disk file having a plurality of disks and a source of organic lubricant mounted within a housing, an air flow stream recirculates within the housing. The vapor pressure of the lubricant source is controlled to provide vapor phase transport of lubricant molecules between the source and the disks' recording surfaces. The lubricant molecules bidirectionally transfer between the air stream and the source, and between the air stream and the surface of the disks, as is needed to maintian a nomo-molecular lubricant film, in the range of about 3 to 15 angstroms, on the disks in accordance with the principle of Langmuir kinetics. The disks are rigid disks and their recording surface includes a carbon overcoat. This overcoat has an affinity for the airborne organic lubricant molecules. In a first embodiment, the vapor pressure of the lubricant is controlled by mounting the material at the coolest location within the housing. In a second embodiment, the lubricant is carried as a mono-molecular layer of lubricant on granular carbon particles which have a surface area that is many times greater than the surface area of the disks. In a third embodiment, the vapor pressure is controlled by combining the lubricant with a vapor pressure diluent.

摘要： A disk cartridge comprises a cartridge case (1) receiving a magnetic disk (2) and a cleaning sheet (3) fixed by spot or line welding to the inner surfaces of the car­tridge case (1) such as to contact both sides of the mag­netic disk (2). The density of the welding spots or lines is reduced or almost no welding spot is formed in the regions (A,B) of the cleaning sheet (3) which undergo pressure exerted by pressing pads on the recording/reproducing apparatus for the disk cartridge.

摘要： The invention relates to a wiper spring (44) attached to a ramp (42) formed in a floppy disc jacket base (18), which biases against a fabric liner (20) to force the fabric liner (20) against the floppy disc (14). The wiper spring (44) is preferably metal, such as phosphor bronze, beryllium copper or stainless steel. The wiper spring (44) is attached to the jacket base (18) by two or more posts (46) in the shell which protrudes through openings (48) formed in the spring (44) and which are peened to hold the spring (44) in place.
