Suspension Design For Attenuation Of Disk Flutter Induced Track Mis-Registration Of A Hard Disk Drive By Manipulation Of Load Beam Pitch Angle

US Patent:
6965500, Nov 15, 2005
Filed:
Feb 22, 2002
Appl. No.:
10/080786
Inventors:
Aaron J. Hanna - San Jose CA, US
Lin Yang - San Jose CA, US
Jin Hui Ou-Yang - San Jose CA, US
Chiao-Ping R. Ku - Fremont CA, US
Assignee:
Western Digital Technologies, Inc. - Lake Forest CA
International Classification:
G11B005/55
US Classification:
360245, 3602451, 3602453
Abstract:
A disk drive includes a head gimbal assembly that includes structure that decreases the pitch angle of the load beam, which decreases disk flutter induced track mis-registration. According to one embodiment, the disk drive includes a body portion including a bore defining a pivot axis; an actuator arm cantilevered from the body portion and a head gimbal assembly (HGA) supported at the actuator arm. The HGA includes a load beam having a first end and a second end, the first end being attached to the actuator arm, the load beam defining a load beam feature near the second end, at least a portion of the load beam feature defining an extension that is parallel to the pivot axis and that has a rectangular cross-section having a length to width aspect ratio that is greater than 1. A slider is coupled to a free end of the load beam extension, and a gimbal coupled to the second end of the load beam and to the slider.

US Patent:
D524634, Jul 11, 2006
Filed:
Aug 25, 2004
Appl. No.:
29/211998
Inventors:
Kenar Yegyayan - Cupertino CA, US
Aaron E. Hanna - Corona CA, US
Assignee:
Newfrey LLC - Newark DE
International Classification:
1105
US Classification:
D 8350

Suspension Design For Attenuation Of Disk Flutter Induced Track Mis-Registration Of A Hard Disk Drive By Manipulation Of The Hinge And/Or Load Beam

US Patent:
7113371, Sep 26, 2006
Filed:
Feb 22, 2002
Appl. No.:
10/080849
Inventors:
Aaron J. Hanna - San Jose CA, US
Lin Yang - San Jose CA, US
Jin Hui Ou-Yang - San Jose CA, US
Chiao-Ping R. Ku - Fremont CA, US
Assignee:
Western Digital Technologies, Inc. - Lake Forest CA
International Classification:
G11B 5/48
G11B 21/16
US Classification:
3602448, 3602442
Abstract:
Disk drives including suspensions and head gimbal assemblies in which the load beam pitch angle is reduced exhibit a reduced disk flutter induced track mis-registration (TMR) at the disk outer diameter. The reduction in the load beam pitch angle may be achieved through variations in the load beam, hinge and/or mount plate configurations, relative positions and/or thickness.
