摘要： In a load/unload type disk drive, when a head for reading/writing information on a disk is retracted outside the disk by a swing arm at the time of stopping the operation of the disk drive, a ramp mechanism holds a lift tab provided at the tip of the swing arm, wherein the ramp mechanism comprises a holding member for holding the lift tab and a mounting member for mounting the holding member thereon, the mounting member having a guide capable of adjusting the mounting position. The holding member mounted on the mounting member is tentatively fastened thereto, with provisions made to be able to adjust the position of the thus mounted holding member by moving it along the guide in a direction conforming to the rotational path of the holding member.

摘要： A recording disk is mounted on a hub in a recording disk drive. The hub is mounted on a rotation shaft. The lower end of the rotation shaft is received on a thrust bearing. The packing is interposed between the enclosure and the thrust bearing. The packing serves to protect the inner space of the enclosure from dust. When the rotation shaft, the hub, the thrust bearing, and the like are assembled into the enclosure, an urging force is applied on the upper end of the rotation shaft. The thrust bearing urges the packing against the enclosure. Since the top surface of the hub is set lower than the top end of the rotation shaft, the urging force is reliably received on the rotation shaft. The alignment cannot be deteriorated between the rotation shaft and the hub.
