摘要： A magnetic disk drive is provided which can attain the reduction in size and thickness without deteriorating the sealing performance for a space defined by a base and a cover. In one embodiment, a cover member is fixed to a base member with fixing screws. An FPC assembly is formed with leg portions extending from respective appropriate positions toward the cover member. The edges of the leg portions are abutted against the cover member fixed to the base member. Further, a stress member is provided between the base member and the FPC assembly. When the cover member is fixed to the base member to urge the FPC assembly adjacent the stress member, the stress member collapses to induce stress from the stress member, whereby a frictional force is generated at abutment surfaces of the cover member and the leg portions, thus fixing the FPC assembly.

摘要： In a magnetic disc apparatus, it is hard to fix a pivot mechanism in a carriage, in view of a mounting space, and in the case that a casing is made of resin, it is hard to fix in accordance with a conventional screwing method in view of a rigidity and a strength. A pivot mechanism (107) is fixed to a base (100) by press fitting a plastically deformable pivot pin (108) of the pivot mechanism (107) to the base (100), passing the pivot pin (108) through a sleeve (107-a) of the pivot mechanism (107) and plastically deforming the pivot pin (108). In the case of dissembling, the pivot pin (108) is pushed out from the base (100) together with a carriage (104), and thereafter the pivot pin (108) is separated from the pivot mechanism (107). Only the pivot pin (108) is disposable.

摘要： In an apparatus for recording continuous information of sound or the like, when a disk device generating a seek sound is used as recording means, such state is prevented that seek sound is mixed as noise and is recorded. In an input processing system of an audio signal in an apparatus for performing sound recording to storage means generating seek noise of the disk or the like, cut-off period 203 is provided by the period when the seek noise 201 is generated, and mixing of the seek noise 201 in the audio signal is prevented, and at the same time, the audio signal during the cut-off period 203 is interpolated by other means or the seek noise level previously set is subtracted.

摘要： In a magnetic disk apparatus, the spindle motor is provided with a hole that penetrates the hub in the axial direction thereof. The hole permits fluid pressure on the outside and inside of the hub to become balanced, reducing the axial fluid force caused by the rotation of the spindle motor. The apparatus further includes a bearing provided with a groove for dynamic pressure generation and a magnetic lubrication fluid which, in combination with a permanent magnet, prevents oil leakage and scattering.

摘要： A storage device includes a partition wall dividing an interior of a casing into a disk chamber and a drive chamber. Recording disks are rotatably disposed in the disk chamber. Arms, each supporting a read/write head at a distal end portion thereof are capable of exteding into the respective spaces between the recording disks through an opening of the partition wall. An actuator is mounted within the drive chamber for linearly reciprocating the arms to cause the heads to skim across recording surfaces of the recording disks. An interrupting surface is formed on a portion of the partition wall at a downstream side of the arm with respect to an air flow due to the rotation of the recording disks, for interrupting the air flow to convert a dynamic pressure of the air flow into a static pressure thereof. With this arrangement, the air is prevented from flowing back from the drive chamber into the disk chamber.
