Magnetic Films Including Iridium, Manganese And Nitrogen
view source
US Patent:

6740398, May 25, 2004
Filed:

Nov 9, 2001
Appl. No.:

10/008646
Inventors:

Christopher Loren Platt - Pittsburgh PA
Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 565
US Classification:

428332, 428692, 428694 TS
Abstract:

Magnetic films comprising iridium, manganese and nitrogen (IrMnN) are disclosed. Multi-layer structures including ferromagnetic layers deposited on the IrMnN films are also disclosed. The IrMnN films have a (200) texture and may act as seed layers and/or exchange biasing layers for the ferromagnetic layers deposited thereon. The multi-layer structures are useful in applications such as read sensors for magnetic recording heads and soft magnetic underlayers for perpendicular magnetic recording media.

US Patent:

7035061, Apr 25, 2006
Filed:

Jun 18, 2003
Appl. No.:

10/464343
Inventors:

Eric W. Singleton - Maple Plain MN, US
David J. Larson - Northfield MN, US
Christopher L. Platt - Pittsburgh PA, US
Kurt W. Wierman - Pittsburgh PA, US
James K. Howard - Pittsburgh PA, US
Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 5/39
US Classification:

36032412, 36032731
Abstract:

A transducing head includes a first bias element, a second bias element, and a magnetoresistive sensor positioned between the first bias element and the second bias element. The first bias element and the second bias element are each formed of a permanent magnet material having a remanent magnetic moment in a range of about 200 to about 800 emu/cm. In a preferred embodiment, the permanent magnet material is an alloy comprising iron, platinum, and at least one material selected from copper, silver, magnesium, lead, zinc, bismuth, and antimony.

US Patent:

8518563, Aug 27, 2013
Filed:

Feb 23, 2010
Appl. No.:

12/711148
Inventors:

Paul M. Jones - St. John VI, US
Xiaoping Yan - Wexford PA, US
Lei Li - Wexford PA, US
James Dillon Kiely - Edina MN, US
Christopher Loren Platt - Fremont CA, US
Michael J. Stirniman - Fremont CA, US
Jiping Yang - San Jose CA, US

Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 5/66
US Classification:

4288333, 4288332
Abstract:

A magnetic data storage medium may include a substrate, a magnetic recording layer, a protective carbon overcoat, and a monolayer covalently bound to carbon atoms adjacent a surface of the protective carbon overcoat. According to this aspect of the disclosure, the monolayer comprises at least one of hydrogen, fluorine, nitrogen, oxygen, and a fluoro-organic molecule. In some embodiments, a surface of a read and recording head may also include a monolayer covalently bound to carbon atoms of a protective carbon overcoat.

20060105203, May 18, 2006
Filed:

Nov 15, 2004
Appl. No.:

10/989030
Inventors:

Lei Li - Pittsburgh PA, US
Christopher Platt - Pittsburgh PA, US
Yiao-Tee Hsia - Wexford PA, US
Assignee:

Seagate Technology LLC - Scotts Valley CA
International Classification:

G11B 5/706
C23C 14/32
B05D 5/12
B05D 1/02
B05D 1/18
US Classification:

428833000, 428848100, 427127000, 204192100, 427256000, 427421100, 427430100
Abstract:

A recording medium for heat assisted magnetic recording includes a magnetic disc having a data zone portion and a non-data zone portion. A liquid lubricant is disposed on the non-data zone portion, and a solid lubricant disposed on the data zone portion. In one embodiment, the solid lubricant has a high thermal stability relative to the liquid lubricant.
