    摘要: An improved spindle motor is provided for rotatably driving one or more memory storage disks in a computer disk drive or the like. The spindle motor comprises a stator shaft having opposite ends anchored to a disk drive housing, and a cylindrical rotor hub supported by bearings from the stator shaft for relatively high speed rotation. The stator shaft carries an armature in magnetically coupled relation with a high strength unitary permanent magnet sleeve carried by the rotor hub, with the number of armature poles and permanent magnet poles being mismatched to achieve low cogging motor operation. The memory disks have central openings therein and are mounted about the rotor hub for rotation during motor operation. Axially elongated resilient shim strips disposed about the rotor hub insure initial disk alignment with their inner diameter edges spaced from direct contact with the rotor hub, thereby permitting the hub and/or disks to accommodate normal thermal gradients during operation without positional shifting of the disks with respect to each other.

    摘要: A station for writing servo track and clock information onto a hard disk drive assembly (HDA) automatically positions and accesses a pallet assembly, including the HDA, in accordance with computerized instructions. A Winchester-type HDA is positioned on the pallet assembly, which in turn is positioned upon a carriage assembly. An automatic, computer-controlled sequence begins which draws the carriage assembly into the station, connects the HDA electronically with the station, and then causes a platten assembly to lift the pallet assembly (with the HDA) into engagement with a top plate assembly. The top plate assembly engages the HDA in a manner wherein the positioning of the HDA actuator assembly is accurately controlled relative to the hard disks located therein. After the hard disks are brought to operational speed utilizing a spindle motor built into the HDA, a clock head assembly positions a clock head to write clock data onto the upper surface of a selected hard disk. A positioner assembly, through an arm assembly, then precisely moves the HDA actuator assembly to erase a face of a hard disk, and then write servo data onto that face utilizing the read/write head of the HDA actuator assembly itself. After the servo data has been applied, the pallet assembly is lowered by the platten assembly, and then withdrawn by the carriage assembly for removal. To assist in disconnecting the HDA from the pallet assembly, ejectors are provided adjacent to a read/write flex connector and to a spindle motor connector on the pallet assembly.

    摘要: An actuator assembly for a computer disk drive includes a pivot shaft which defines a pivot axis for the actuator assembly, a pivotable actuator which encircles the pivot shaft, a bearing assembly disposed between the pivot shaft and the actuator, and a labyrinth seal adjacent to a lower edge of the bearing assembly. The labyrinth seal is incorporated into the pivot shaft and includes an axially extending ridge which is disposed in facing relation to a lower edge of the bearing assembly. The labyrinth seal also includes a reservoir disposed radially inwardly of the axially extending ridge, and a flange which extends radially outwardly of the axially extending ridge. The flange includes both axially and radially-facing surfaces which are disposed in facing relation to oppositely facing surfaces of the actuator. Very small air gaps are maintained between the labyrinth seal and the actuator assembly, on the order of 0.003 to 0.005 inch, in order to eliminate or minimize any actuator bearing lubricant migration or out-gassing into the disk drive assembly. An actuator shaft washer seal is provided adjacent to the upper edge of the bearing assembly. The actuator shaft washer seal is fixed to the actuator and extends radially inwardly toward the pivot shaft.

    摘要: A computer disk drive unit includes a housing having a lower base and an upper removable cover which define a disk storage compartment therebetween. A shaft fixed to the lower base supports a plurality of memory storage disks for rotation within the disk storage compartment. An elastomeric snubber extends between an upper end of the shaft and the upper housing cover, for preventing direct contact and absorbing vibration between the shaft and the upper housing cover. The snubber is a cylindrical member having a lower solid section disposed within a recess in the upper end of the shaft, and an upper tubular section which is compressed as the upper housing cover is secured to the lower base. The upper housing cover includes a thickened portion whereat the upper tubular section of the snubber contacts the cover.

    摘要: A disk array includes a mainframe chassis conforming to standard SCSI disk drive mechanical form factors, and a mother board and a RAID controller within the chassis. The chassis includes a pivotable access door shock absorber mounted on an inside surface of the door which permits electronic modules to be placed within the chassis, and which helps to control mechanical shock between the chassis and the enclosed electronic modules. The mother board interconnects electrical signals between the electronic modules, at least some of which comprise disk drives forming a redundant array of independent, or inexpensive, disks (RAID). One of the electronic modules is a secondary power supply module which is connectable to the mother board. The RAID controller is electrically connected to a system host power supply and a host interface bus, and through the RAID controller the mother board interconnects all the electrical signals between the system host power supply and the host interface bus with the secondary power supply module and the RAID disk drives.
