Head Shock Resistance And Head Load/Unload Protection For Reducing Disk Errors And Defects, And Enhancing Data Integrity Of Disk Drives

View page
US Patent:
6995952, Feb 7, 2006
Filed:
Mar 12, 2001
Appl. No.:
09/804105
Inventors:
Norbert A. Feliss - Sunnyvale CA, US
Yiyun Huang - Milpitas CA, US
Jennifer Lu - San Jose CA, US
Wing Tsang Tang - Palo Alto CA, US
Assignee:
Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam
International Classification:
G11B 5/60
US Classification:
3602353
Abstract:
A slider in a disk drive is shock-protected with an overcoat layer of either metal or polymer directly on the areas of the slider that are prone to contact the disk when the slider is loaded off the platform, or when the slider is shocked while in operation over the data zone of the disk. The material used to form the layer absorbs shock and reduces wear, and is bonded or sputtered to the head in a region other than the pads of the air bearing surface. This region is typically the reactive ion etched (RIE) surface area and is slightly below the pads of the air bearing surface of the head. In an alternate version of the invention, the slider is protected by covering only the edges of the slider with a suitable material. Finally, the entire slider may be encased with the overcoating except for the pads of the air bearing surface.

Methods And Apparatus To Detect Surface Characteristics On Magnetic Read/Write Heads

US Patent:
7982987, Jul 19, 2011
Filed:
Dec 8, 2008
Appl. No.:
12/329719
Inventors:
Youping Deng - Saratoga CA, US
Randall G. Simmons - San Jose CA, US
Wing T. Tang - Palo Alto CA, US
Huiping Yang - JiangXi, CN
Assignee:
Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam
International Classification:
G11B 27/36
G11B 21/02
G11B 5/02
US Classification:
360 31, 360 25, 360 75
Abstract:
A method and apparatus for detecting predetermined surface characteristics in head gimbal assemblies to improve hard disk drive reliability. The predetermined surface characteristics include head slider protrusions such as scratches or contamination that can cause damage to the head or disk in hard drives. By detecting these protrusions, those drives with an increased chance of failure can be removed from a test group, thereby increasing the quality and reliability of the remaining disk drives. The invention provides a method of detecting these protrusions that is a more practical option than using a scanning electron microscope (SEM) to inspect each head slider.
