US Patent:
6579612, Jun 17, 2003
Filed:
Jun 24, 1999
Appl. No.:
09/344004
Inventors:
Jeffrey S. Lille - San Jose CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 566
US Classification:
428332, 428336, 428692, 428694 R, 428694 T, 428694 TS, 428694 TM, 428900, 338 32 R, 324209, 324235, 324262, 73776, 73779
Abstract:
A sensor for measuring magnetostriction of and/or magnetic thin film is constructed by depositing a thin film nonferromagnetic electrically insulating layer followed by a thin film layer of a sensor material which is piezoresistive and nonferromagnetic. The insulating and the piezoresistive film can be etched into an appropriate pattern and orientation to provide sensitivity to strain in the magnetic film. The magnetostrictive strain in the magnetic film is induced by a known magnetic field which produces a corresponding strain in the piezoresistive film which can be measured as a change in the electrical resistance which can be detected by external probes or other measuring means. The measurement of the magnetostriction can be performed as a part of the manufacturing process for wafers with a plurality of thin film magnetic heads thereon and does not require that the wafers be removed to a laboratory.

Enhanced Silicon And Ceramic Magnetoresistive Read/Write Head And A Method For Producing The Same

View page
US Patent:
6587314, Jul 1, 2003
Filed:
May 16, 2000
Appl. No.:
09/572025
Inventors:
Jeffrey S. Lille - San Jose CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 539
US Classification:
360313, 3602344, 3602347, 3602351
Abstract:
An enhanced silicon and ceramic magnetoresistive read/write head and method for making the same is disclosed. The present invention provides reliable chemical mechanical polish etch stop by etching deep trenches into the silicon at the surrounding edges of the magnetic write and read device and filling it with a refractory metal (e. g. tungsten) so that the silicon wafer thickness will not significantly add to the length of the ABS nor to the gram load of the slider. An imbedded deformable pad will allow these bonded heads to have a high average fly height and reduce to near contact recording when reading and writing through an applied potential across a deformable pad in the silicon. The epoxy bond of the silicon to the ceramic slider consists of polymethyl methracrylate (PMMA) which can be spun on a wafer or a row of wafers with nanometer thickness repeatability and using low temperatures, i. e. , 200° C.

View page
US Patent:
6680832, Jan 20, 2004
Filed:
May 11, 2001
Appl. No.:
09/853352
Inventors:
Kuok San Ho - Cupertino CA
Jordan A. Katine - San Jose CA
Jeffrey S. Lille - Sunnyvale CA
Ching H. Tsang - Sunnyvale CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 539
US Classification:
3603242, 360319
Abstract:
A current-perpendicular-to-the-plane (CPP) magnetoresistive sensor or read head has a magnetic shield geometry that covers the side walls of the sensor structure to prevent side reading caused by magnetic flux entering from adjacent data tracks. The shield geometry includes a bottom shield with a substantially planar surface and a specially shaped top shield. The top shield has substantially vertical portions generally parallel to the side walls of the sensor structure, a horizontal top portion over the trackwidth region of the sensor, and horizontal side portions formed over the portions of the bottom shield on either side of the sensor structure. The insulating gap material that separates the bottom and top shields is in contact with the horizontal portions of the bottom shield and the side walls of the sensor structure.

Simultaneous Definition And Direct Transfer Of A Write Head Pole And Coil For A Magnetic Read/Write Head

View page
US Patent:
6696226, Feb 24, 2004
Filed:
Nov 8, 2002
Appl. No.:
10/290747
Inventors:
Thomas Edward Dinan - San Jose CA
Jeffrey S. Lille - Sunnyvale CA
Hugo Alberto Emilio Santini - San Jose CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 5147
US Classification:
430320, 430314, 430319, 2960307, 2960325
Abstract:
A method of making a magnetic read/write head using a single lithographic step to define both a write coil and a pole tip structure. The use of a thin image resist layer over a hard reactive-ion etch mask and image transfer techniques allows very high resolution optical lithography which can accommodate formation of a very compact coil and pole structure. The use of a single high resolution lithography step on a planarized structure to define both a write pole tip and a write coil coplanar with the write pole tip avoids the problems of reflective notching associated with lithography to define the pole tip in the vicinity of non-planar features of the coil structure and also eliminates alignment inaccuracies inherent in separate lithography processes for the coil and pole.

Slider Head Having Thermally Controlled Distal End And Assembly With A Rotating Disc

View page
US Patent:
6775103, Aug 10, 2004
Filed:
Apr 2, 2001
Appl. No.:
09/824351
Inventors:
Jeffrey S. Lille - Sunnyvale CA
Assignee:
Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam
International Classification:
G11B 560
US Classification:
3602365, 3602353
Abstract:
A slider head assembly is provided which includes a slider head for reading/writing data on the surface of a rotating disc. The slider head is disposed in spaced relationship with respect to the disc for read/write (R/W) operations. The slider head assembly is comprised of a body portion having an essentially planar surface positioned to co-act with the surface of the disc with a proximal end and a distal end. The proximal end or trailing slider surface of the head assembly has a read/write element thereat. The distal end or leading slider surface of the assembly has an actuation device mounted thereon, having a surface the position of which can be modified by an external signal to change the position of the head with respect to the planar or air bearing surface (ABS) of the head assembly. This will change the characteristics of the boundary layer of air between the rotating disc and the head, causing the head assembly to move closer to or farther from the rotating disc when actuated by the external signal. A preferred embodiment is a patterned heating element which selectively heats the edge of the leading surface of the slider to cause position modification of the device.
