  • System, method and apparatus for disk drive recirculation filter having inlet and outlet disk rim shrouding
    Patent number: 8102618
    Abstract: A hard disk drive has a recirculation filter that shrouds the rims of disks at the inlet and outlet of the filter. The shroud is aerodynamically shaped to reduce flow-induced disk vibration of the read/write head. A significant improvement in non-repeatable run-out is provided when the inlet and outlet are shrouded along the rims of the disks.

  • Coil wire lubricant for use in magnetic disk drives
    Patent number: 6392846
    Abstract: A coil assembly for disk drive components is presented which includes a coil winding free of lubricants that cause stiction problems during the operation of the disk drive assembly. An actuator coil and spindle motor winding are disclosed which include a conductor, an insulating layer over the conductor, a bond coat overlying the insulating layer, and a lubricant coating on the insulating layer. The lubricant coating is a hydrocarbon based oil having a molecular weight within ranges that will not volatilize and condense on the surface of the disks in the drive.

  • Magnetic disk drive with load/unload structure including a base, a body, ramps, and a H/L ratio of 2 or greater
    Patent number: 6181528
    Abstract: The present invention is a magnetic disk drive for reading or writing magnetically, comprising: (i) a base plate; (ii) a plurality of magnetic disks; (iii) a hub fixedly attached to the disks for supporting the disks; (iv) a motor operable to rotate the hub; (v) a plurality of magnetic read/write heads, each associated with the surface of a disk; (vi) an actuator for supporting the heads and moving the heads across the disks; (vii) a support shaft attached to the base plate; and (viii) a load/unload structure for displacing the heads from the disk comprising an elongated body, a base portion fixedly attached to the base plate and a plurality of ramps extending outwardly from the body. The body of the structure is mounted through one or more holes in the body onto the support shaft so that the support shaft extends along the length of the body to support the structure.
