Appl. No.:

10/108293

Inventors:

Jean Ling Lee - San Jose CA

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

C23C 1434

US Classification:

20419216, 20419212, 134 34, 427131, 427331, 4274071, 430320, 2504923

Abstract:

A magnetically patterned hard disk is made by sputtering the magnetic layers, sputtering the carbon layer, applying a nonfunctional lubricant, buff/wiping the disk to remove sputtering debris and asperities, removing the nonfunctional lubricant using a standard degreasing process, applying and patterning a resist, and thereafter subjecting the exposed disk to inert ion irradiation.

US Classification:

428828, 428829, 4288312, 427599

Abstract:

A method of manufacturing a perpendicular magnetic recording medium, comprises steps of: (a) providing a substrate of an amorphous thermoplastic polymer material having softening and glass transition temperatures as low as about 95 C. ; and (b) forming at least one stack of thin film layers atop at least one surface of the substrate, the at least one layer stack including at least one granular magnetic recording layer of perpendicular type, wherein oxides and/or nitrides provide physical de-coupling of adjacent magnetic grains; and wherein each of the thin film layers is formed by depositing at a substrate temperature not greater than about 70 C. , and the coercivity (H) of the resultant perpendicular magnetic recording medium is at least about 4,000 Oe.

Inventors:

Charles Fredrick Brucker - Pleasanton CA, US
Jean Ling Lee - San Jose CA, US

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 5/66
G11B 5/70

US Classification:

428832, 4288312

Abstract:

Generally, methods and apparatus are disclosed for fabrication of angle-of-incidence layers on a substrate. In one embodiment, the angle-of-incidence layers may have either radial or circumferential tilt symmetry, using, for example, sputtering or evaporation techniques. In one example, an apparatus for sputtering material comprises a substrate support member, a cathode positioned in substantially facing relationship with respect to the substrate support member and a shutter plate. The shutter plate is disposed between the substrate support member and the cathode and defining an aperture for selective transmission of sputtered articles from the cathode on the basis of a non-perpendicular trajectory angle relative to a plane of the substrate support member.

Inventors:

Jean L. Lee - San Jose CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H01T 23/00

US Classification:

361231

Abstract:

Embodiments provide various apparatus and techniques for deflecting or redirecting a flow of ionized air generated from an ionic wind generator. In general, a deflection field generator can be located proximate to the path of the flow of ionized air. The deflection field generator is configured to generate an electromagnetic field, which deflects a least a portion of the flow of ionized air to a different path and may possibly increase local heat transfer.

International Classification:

H01F 7/20
H01F 7/02

US Classification:

335285, 335306, 439 39

Abstract:

A plug or connector including a coded magnet and an electrical contact. As the plug approaches a corresponding port, the coded magnet interacts with a magnet within the port. The interaction between the plug coded magnet and the port coded magnet provides a force to connect and/or align the plug with the port. Once the plug is received within the port, if a process is completed, the coded magnets polarities are altered to eject the plug from the port.
