Burnishing Tape Testing Method And Device

US Patent:
6408678, Jun 25, 2002
Filed:
Oct 13, 2000
Appl. No.:
09/687673
Inventors:
Manoj Chopra - Campbell CA
Charles H. Lee - San Jose CA
Thorsten Lohmeyer - Woerrstadt, DE
Jay Allan Merz - Aromas CA
Hoa-Binh Tu - San Jose CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G01N 356
US Classification:
73 9, 73862393
Abstract:
The method for testing burnishing tape includes placing the tape on a backing surface and applying a force normal to the abrasive surface of the tape in a localized area of the tape surface. Thereafter, an increasing pulling force is applied to the end of the tape up to a point where the tape moves under the effect of the normal force. Through prior burnishing tape product testing a known normal force N is determined and a delamination pulling force D is likewise determined, such that a burnishing tape can be said to be defective where it is placed under a normal force N and the pulling force required to move it is less than the delamination pulling force D. The values of N and D are determinable for different types of burnishing tape and thereafter utilizable to test further quantities of similar burnishing tape. The testing device of the present invention includes a tape supporting plate, a force gauge for applying a known normal force N to the abrasive surface of the burnishing tape disposed on the plate, and a variable torque motor with a torque sensor that is utilized to apply a known variable pulling force to the tape, such that the pulling force required to move the tape under the normal force N can be determined and then compared to the predetermined delamination force D. Where the pulling force required to move the tape is less than D the tape is determined to be defective, whereas when the pulling force required to move the tape is greater than D the bonding strength of the abrasive layer of the burnishing tape is determined to be adequate such that the burnishing tape can be confidently utilized to burnish hard disk surfaces.

System, Method And Apparatus For Lapping Workpieces With Soluble Abrasives

US Patent:
7758403, Jul 20, 2010
Filed:
Nov 16, 2007
Appl. No.:
11/941282
Inventors:
Manoj Chopra - Union City CA, US
Glenn Paul Gee - San Jose CA, US
Xavier Charles Lelong - San Jose CA, US
Assignee:
Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam
International Classification:
B24B 1/00
US Classification:
451 36, 451103
Abstract:
A soluble abrasive is used to lap workpieces to overcome the problem of embedding and retaining abrasive particles in the workpieces. The soluble abrasives are dissolved from the workpiece even if they become embedded in the workpiece. For example, the abrasives may be dissolved with water and comprise ionic salts. The soluble abrasive has a hardness that is equal to or slightly greater than the hardness of the metal being lapped.

Controlling Bond Pad Migration In A Direct Access Storage Device

US Patent:
2008018, Jul 31, 2008
Filed:
Jan 31, 2007
Appl. No.:
11/701038
Inventors:
Manoj Chopra - Union City CA, US
Eric W. Flint - San Jose CA, US
Jeffrey P. Gunder - Los Altos CA, US
Victor H. Perez - Mexico, MX
Doug Williams - San Jose CA, US
International Classification:
G11B 15/64
US Classification:
360237
Abstract:
A slider assembly used in a direct access storage device includes electrically conductive bond pads formed on the slider body. A rigid and electrically non-conductive material surrounds and abuts the bond pads. The material and the bond pads form a planar surface. The material prevents the bond pads from migrating and shorting, so that the bond pads can be placed closer together.
