US Patent:

6643103, Nov 4, 2003
Filed:

Jan 5, 2001
Appl. No.:

09/755019
Inventors:

Isabel G. Trindade - Pittsburgh PA
Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 539
US Classification:

360314
Abstract:

A dual spin valve read head includes first and second spin valve stacks configured to operate in a current perpendicular to plane (CPP) mode. The first and the second spin valve stacks each include a free layer. A spacer is positioned adjacent the free layers of the first and the second spin valve stacks and spaces the first spin valve stack apart from the second spin valve stack.

US Patent:

6765767, Jul 20, 2004
Filed:

Nov 15, 2001
Appl. No.:

09/999286
Inventors:

Isabel G. Trindade - Pittsburgh PA
Michael A. Seigler - Pittsburgh PA
Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 539
US Classification:

360319, 360322
Abstract:

A read head for use with magnetic recording media having a plurality of magnetic tracks includes a read sensor, first and second magnetic lead shields for improving track resolution, and first and second magnetic shields for improving linear resolution. The read sensor is formed on a side wall of one of the first and second magnetic lead shields using a technique such as ion beam deposition for enhanced film growth rate on the side wall. A magnetic disc drive storage system incorporating the read head and a method of making the read head are also included.

Filed:

Feb 2, 2001
Appl. No.:

09/776435

Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 5127
US Classification:

360319
Abstract:

A ferromagnetic shield material having a minimized anisotropic magneto-resistance effect permits the use of a combined shield/electrical lead for magneto-resistive read elements. The shields/electrical leads may therefore be placed closer together, maximizing the recording density that may be read by a magnetic recording head using a read element having such shields/leads.

US Patent:

7050274, May 23, 2006
Filed:

Dec 10, 2001
Appl. No.:

10/012829
Inventors:

Michael A. Seigler - Pittsburgh PA, US
Isabel G. Trindade - Pittsburgh PA, US
Paul E. Anderson - Eden Prairie MN, US
International Classification:

G11B 5/39
G11B 5/127
US Classification:

36032411, 36032723, 36032731, 36032412
Abstract:

Multilayer permanent magnet films comprising at least two permanent magnet layers separated by an interlayer are disclosed. In one embodiment, the multilayer permanent magnet film includes an interlayer deposited on a first permanent magnet layer, a seed layer deposited on the interlayer, and a second permanent magnet layer deposited on the seed layer. The permanent magnet layers may comprise a material such as CoPt, while the seed layer may comprise a material such as TiW. The interlayer may comprise a material such as Ta. The multilayer permanent magnet films possess favorable properties such as high magnetic coercivity (H) and high remnant magnetization (M) at thicknesses which yield high magnetic fields. The films may be used in applications such as current perpendicular to the plane (CPP) magnetic sensors in which the multilayer permanent magnet film is used to magnetically bias the sensor.

US Patent:

6621664, Sep 16, 2003
Filed:

Feb 28, 2001
Appl. No.:

09/795581
Inventors:

Isabel Goncalves Trindade - Pittsburgh PA
Gregory John Parker - Gibsonia PA
Sharat Batra - Wexford PA
Robert Rottmayer - Wexford PA
Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 539
US Classification:

360318, 360313, 360314
Abstract:

An integrated read/write perpendicular recording head facilitates the use of magnetic storage media having a high magnetic recording density and high data rates. The use of a perpendicular write portion provides adequate space between the main and opposing poles for a read element and associated electrical contacts therebetween. The use of a differential dual spin valve as a read element eliminates the need for magnetic shielding of the read element. Such a structure permits the read element and main write pole to be close together, thereby minimizing seek time, and permitting rapid transition from read to write operations, and vice versa.
