Tester With Virtual Ground

US Patent:
8004782, Aug 23, 2011
Filed:
Mar 19, 2009
Appl. No.:
12/407619
Inventors:
Michael Nojaba - Gustine CA, US
Pradeep K. Thayamballi - Fremont CA, US
James Tze-Hwa Tung - Atherton CA, US
Julius A. Turangan - Livermore CA, US
Assignee:
Western Digital Technologies, Inc. - Irvine CA
International Classification:
G11B 27/36
G11B 33/14
G11B 5/33
G01R 33/00
US Classification:
360 31, 360 9702, 360323
Abstract:
A tester system includes a tester and a radioactive isotope source. The tester includes a spindle assembly, a disk mounted to the spindle assembly, and a head actuatable over the disk. The radioactive isotope source is positioned in an ionizing location proximate the tester, such that a minimum distance between the radioactive isotope source and an axis of rotation of the disk is less than a radius of the disk.

Method For Defining A Touch-Down Power For Head Having A Flying Height Actuator

US Patent:
7440220, Oct 21, 2008
Filed:
May 29, 2007
Appl. No.:
11/754606
Inventors:
Michael Nojaba - Milpitas CA, US
Rex Niedermeyer - Newark CA, US
Assignee:
Western Digital (Fremont), LLC - Fremont CA
International Classification:
G11B 21/02
US Classification:
360 75
Abstract:
A novel method for defining a touch-down power for a head that has a head-based flying height actuator is disclosed and claimed. A linear relationship between power and spacing is derived by fitting to first and second transducer-disk spacings corresponding to first and second electrical powers applied to the head-based flying height actuator. A third spacing between the transducer and the disk is determined when a greater third electrical power is applied to the flying height actuator. An estimated third spacing between the transducer and the disk, corresponding to application of the third electrical power to the flying height actuator, is calculated using the derived linear relationship and the third electrical power. The touch-down power is defined to be substantially equal to the second electrical power if an error between the third spacing and the estimated third spacing is larger than a first threshold.
