摘要： A disk drive apparatus is constructed with a filter attached to an enclosure through a through hole formed in the enclosure. A special positioning operation is eliminated by inserting the filter into the through hole because a portion of the filter is exposed to the outside through the enclosure. The disk drive apparatus can be constructed so that the filter is supported on the enclosure. In this case, the enclosure has a chamfered portion around the circumference of the through hole; the filter has a flange corresponding to the chamfered portion; and the flange is brought into contact with the chamfered portion. The filter can be fixed to the enclosure by sticking adhesive tape on a circumference of the flange and a circumference of the chamfered portion of the enclosure. Adhesive residue is eliminated because the fixation of the filter is performed with single-coated tape.

摘要： A disk clamp has a data position in a recording track that is resistant to positional deviations even after temperature cycling is conducted. The distribution of data positions can be centered in the vicinity of the center position. A disk top clamp and hub are made from materials that are stable in terms of chemical properties over a temperature range in which the disk recording apparatus is used and have such a coefficient of elasticity that a clamping force required to clamp the recording disks while the disk recording apparatus is in use can be obtained from the tightening force to tighten the screws. The material of the top clamp and the hub has a thermal expansion coefficient that is close to that of the recording disk.

摘要： When an HDD is subjected to shock with a magnetic head (22) retracted to the parking zone, a suspension (34) having a magnetic head (36) at the free end thereof swings. When a lowest suspension (34) swings, the free end of the suspension (34) is brought into contact with a pin projection (50) and further displacement toward the base (12) is impeded. The suspension (34) that further swings in this condition presents not a swing in a primary mode (cantilever support mode) but a swing in a secondary mode (two-point support mode), and the maximum displacement of the suspension (34) occurs at the longitudinal intermediate portion of the suspension (34). The intermediate portion that is displaced is made to go into a groove (48), and the contact of the intermediate portion of the suspension (34) with the base (12) is impeded by the groove (48).
摘要翻译：当HDD被收回到停车区的磁头（22）受到冲击时，在其自由端处具有磁头（36）的悬架（34）摆动。当最低的悬架（34）摆动时，悬架（34）的自由端与销突起（50）接触，并且朝向基座（12）的进一步的位移被阻碍。在这种情况下进一步摆动的悬架（34）在初级模式（悬臂支撑模式）中不摆动，而是在二次模式（两点支撑模式）下摆动，并且发生悬架（34）的最大位移在悬架（34）的纵向中间部分处。使位移的中间部分进入凹槽（48），并且悬架（34）的中间部分与基部（12）的接触被凹槽（48）阻挡。

摘要： The present invention provides an integrally formed ramp that is used for evacuating the suspension arm of a data storage device. The ramp has sliding portions, each having guiding zones and a landing zone. The boundary between the guiding zones and the landing zone is formed parallel to a reference line, so even if the landing portion had a recessed shape, the sliding portion could be molded with a casting mold by pulling out the casting mold in the direction of the reference line. The necessary portion of a support portion which is formed with the same casting mold as the sliding portions is formed so as not to disturb the pulling-out of the casting mold in the direction of the reference line. The integrally molded ramp is high in fabrication accuracy and excellent in defining an accurate loading/unloading position of the suspension arm.

摘要： In a hard disk drive, power and signals are transferred through a flexible cable 42 between a carriage having a magnetic head reading magnetic information while the positioning of the magnetic head is controlled on a magnetic disk and a card provided on the lower surface of a base. The movable section 44 of the flexible cable 42 is supported by the carriage to follow the carriage. A nonmovable section 46 is bent so as to enclose a reinforcement plate 50 and installed on the base through the reinforcement plate 50. The reinforcement plate 50 is used as a reinforcement for installing an AE module 54 on the upper surface 52 thereof. The reinforcement plate is also used as a reinforcement for connecting a carriage connector 84 to the card 40 through the lower surface 60 thereof. The reinforcement plate is used for maintaining an attitude to maintain the attitude of the movable section 44 in the lateral direction on a surface 64 of thickness of the plate. One reinforcement plate is needed for performing these operations.

摘要： A ramp wherein the amount of deformation in the front end edges of guiding parts caused by thermal expansion. The ramp includes at least two guiding parts individually formed for each suspension arm and made of a polymeric material having a small friction coefficient for guiding the suspension arm by sliding into a accommodation zone, and a guide supporting member made of a material having a thermal expansion coefficient smaller than that of the polymeric material of the guiding part for supporting each guiding part at a predetermined position. The guide supporting member has guide support holes which are located in zones to be contacted with the associated guiding parts, are not contacted with associated recording disks, and are engaged with the associated guiding parts at such positions that distances to the front end edges of the guiding parts become shortest. Each of the guiding parts has a projection. When the projection is engaged in the associated guide support hole, the guiding part guides the suspension arm at a suitable position.
