摘要： A device streamlines air flow inside a hard disk drive with a stationary afterbody that is located adjacent to each of the disks. A diverter portion of the device enhances the volumetric flow of air through a diffuser and a contraction. The overall function of the device effectively expands the air flow so that the speed of the air flow gradually decreases while pressure increases. This design reduces losses in system momentum due to sudden expansion of the air in the drive. In addition, air flow moving toward the disk pack may be contracted to allow efficient energy conversion from pressure energy to kinetic energy prior to merging of the bypass air flow with the air flow among the disks.

摘要： A system for locating and determining the orientation of fasteners in hard disk drive spindle assemblies utilizes a sensor system that facilitates an automated rework process for the spindle assemblies. The screw locating system identifies the locations of the screws in a spindle and generates a signal for a screw driver system to align tool bits with the screws. The sensor is highly advantageous when reworking spindle motors with opaque labels that cover and/or block the fasteners. The present invention overcomes the drawbacks of prior art techniques by using a screw locating system that is based on a selected capacitance probe without requiring the use of timing features.

摘要： A disk clamp for securing data storage disks to the hub of a spindle motor in a hard disk drive has a circumferential rib protruding from a lower surface of the disk clamp. A complementary recess is formed in the hub of the spindle motor for closely receiving the rib on the disk clamp. The inner diameter of the rib and the outer diameter of the recess are closely toleranced to provide a very precise centering feature for mounting and aligning the disk clamp with respect to the hub and spindle motor. This design reduces the complexity of the tooling and fixtures required to complete the assembly and the overall part cost is reduced.

摘要： A system, method, and apparatus for solving flow-induced track misregistration (TMR) problems in hard disk drives (HDD). Boundary layer manipulation techniques are applied to the airflow in the HDD, such as boundary layer suction with slots or holes, and wall damping techniques, such as an open honeycomb seal and Helmholtz resonators. These flow-conditioning solutions reduce the turbulence intensity throughout the HDD to reduce TMR. These solutions achieve these goals while minimizing increases in the running torque needed to overcome their inherent rotational drag.

摘要： A device streamlines air flow inside a hard disk drive with a stationary afterbody that is located adjacent to each of the disks. The device gradually expands the air flow so that the speed of the air flow gradually decreases while pressure increases. This design reduces losses in system momentum due to sudden expansion of the air in the drive. In addition, air flow moving toward the disk pack may be contracted to allow efficient energy conversion from pressure energy to kinetic energy prior to merging of the bypass air flow with the air flow among the disks. The device has a comb-like structure that is offset from the disk pack in the radial direction. The structure fulfills an aerodynamic function, reduces track misregistration, lowers overall aerodynamic dissipation, and fulfills a filtration function.

摘要： An apparatus and method for guiding bypass reentry flow through contraction and filter in a hard disk drive. The method provides a bypass channel for directing airflow away from a first portion of a disk of the hard disk drive and toward a second portion of the disk of the hard disk drive. A contraction portion is coupled with the bypass channel at a location wherein the bypass channel directs the airflow back toward the second portion of the disk of the hard disk drive. The contraction portion accelerates a first portion of the airflow directed toward the second portion of the disk of the hard disk drive. A filter portion integral with the contraction portion is utilized for filtering a second portion of the airflow directed toward the second portion of the disk of the hard disk drive.

摘要： An embodiment of the invention clamp assembly for a disk which includes a cavity for trapping the excess lubricant which migrates from the load bearing threads of the screws that hold the assembly in place. In a preferred embodiment a flexible structure, called a screw lubricant trap, is included between a clamp and hub. A recess for the screw lubricant trap is formed in one or both of the mating surfaces of the clamp and/or the hub. The screws are arranged in the interior of the screw lubricant trap, so that when the hub is spinning, the excess lubricant is forced into the cavity to kept the excess lubricant from migrating onto the disk. The screw lubricant trap is preferably made to be non-load bearing to avoid affecting the load on the screw. Alternatively, a groove can be machined in the clamp to serve as the lubricant trap.
