US Patent:

6342991, Jan 29, 2002

Filed:

Dec 27, 1999

Appl. No.:

09/472640

Inventors:

Shantanu Dattatrey Joshi - Fort Collins CO
Thomas Michael Durrum - Broomfield CO
Darrel Ray Culver - Longmont CO

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 2122

US Classification:

3602561, 360 9702

Abstract:

An apparatus for increasing the operative force on an air vane latch apparatus in a disc drive includes an air gate having an elongated rib extending parallel to the air vane immediately downstream of the air vane for reducing pressure behind the air vane during disc drive operation to reduce the disc speed at which the latch apparatus moves from a latched position to an unlatched position. The air gate is preferably a rib extending along an underside surface of the head disc assembly cover positioned parallel to the air vane and immediately downstream.

Appl. No.:

10/842198

Inventors:

Darrel Ray Culver - Longmont CO, US

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 5/55
G11B 21/08

US Classification:

3602656

Abstract:

A bearing assembly to mount an actuator on a mounting hub of a data storage device comprises a cylindrical hub for the actuator having an internal bore along a cylindrical hub axis. The bearing assembly also has one or more bearings mounted inside the internal bore of the cylindrical hub and a sleeve mounted inside the one or more bearings so that the cylindrical hub rotates relative to the sleeve. The sleeve is adapted to contact a mounting hub. A single piece captive screw is retained within the sleeve and is free to rotate about the cylindrical hub axis independent of the sleeve to engage the mounting hub and tighten the sleeve to the mounting hub.

Abstract:

A solid-state drive (SSD) includes a first rigid printed circuit board comprising a surface that defines a first plane. A second rigid printed circuit board of the SSD comprises a surface that defines a second plane that is substantially parallel to the first plane. A flexible interconnect couples the first rigid printed circuit board and the second rigid printed circuit board. The flexible interconnect partially encloses a volume. A capacitor is disposed within the volume.
