Appl. No.:

10/260896

Jinqiu Zhang - Fremont CA, US
Jing Zhang - San Jose CA, US
Yiming Huai - Pleasanton CA, US

Assignee:

Western Digital (Fremont), Inc. - Fremont CA

International Classification:

G11B005/39

US Classification:

360322

Abstract:

Magnetoresistive (MR) sensors are disclosed that have leads that overlap a MR structure and distribute current to and from the MR structure so that the current is not concentrated in small portions of the leads, alleviating the problems mentioned above. For example, the leads can be formed of a body-centered cubic (bcc) form of tantalum, combined with gold or other highly conductive materials. For the situation in which a thicker bcc tantalum layer covers a highly conductive gold layer, the tantalum layer protects the gold layer during MR structure etching, so that the leads can have broad layers of electrically conductive material for connection to MR structures. The broad leads also conduct heat better than the read gap material that they replace, further reducing the temperature at the connection between the leads and the MR structure.

Abstract:

Side shield structures magnetically shielding a read sensor to block side reading of tracks on a magnetic media. The read heads include bottom and top magnetic shield layers, a read sensor or magnetically sensitive element between the bottom and top magnetic shield layers, and a side shield assembly formed of magnetically shielding material positioned between the bottom and top magnetic shield layers and adjacent at least a portion of the read sensor. In current-in-plane embodiments, the side shield assembly includes a pair of side shields of magnetically shielding material adjacent a lower portion of the read sensor formed on a lower read gap. In current-perpendicular-to-plane embodiments, the side shield assembly includes a pair of side shields extending from the bottom magnetic shield adjacent lower sides of the read sensor and/or a pair of side shields extending from the top magnetic shield adjacent upper sides of the read sensor.

International Classification:

G11B 5/39

US Classification:

360322

Abstract:

Magnetoresistive (MR) sensors have leads that overlap a MR structure and distribute current to the MR structure so that the current is not concentrated in small portions of the leads. An electrically resistive capping layer can be formed between the leads and the MR structure to distribute the current. The leads can include resistive layers and conductive layers, the resistive layers having a thickness-to-resistivity ratio that is greater than that of each of the conductive layers. The resistive layers may protect the conductive layers during MR structure etching, so that the leads have broad layers of electrically conductive material for connection to MR structures. The broad leads conduct heat better than the read gap material that they replace, further reducing the temperature at the connection between the leads and the MR structure.

Abstract:

A method for forming a hard bias structure in a magnetoresistive sensor is disclosed. A magnetoresistive sensor having a soft magnetic bias layer, spacer layer, and a magnetoresistive layer, is formed over a substrate having a gap layer. A mask is formed over a portion of the magnetoresistive sensor structure to define a central region. The masked structure is ion milled to remove portions not shielded by the mask, to form the central region with sloped sides, and to expose a region of the gap layer laterally adjacent the sloped sides. A first underlayer is deposited onto at least the sloped sides at a high deposition angle. A second underlayer is deposited to at least partially overlap the first underlayer, and at a first lower deposition angle. A hard bias layer is deposited over at least a portion of the second underlayer, and at a second lower deposition angle.

International Classification:

G06F 17/30

US Classification:

707 6, 707 7

Abstract:

To perform multi-pattern searching, a preprocessing engine populates a SUFFIX table, a PREFIX table and a PATTERN table. The SUFFIX table combines data conventionally stored in SHIFT and HASH tables. Pointers in the SUFFIX table refer to corresponding segments in the PREFIX table. Each PREFIX table segment is sorted by a prefix hash. A PATTERN table includes a hash of each full pattern sorted and grouped into segments, with each segment corresponding to a suffix hash and prefix hash combination. Pointers in the PREFIX table refer to corresponding segments in the PATTERN table. The PREFIX and PATTERN can be kept in secondary storage, allowing potentially billions of patterns to be used. After preprocessing, patterns are evaluated against a source file. A document metric is determine to qualitatively describe the similarity between the source file and each pattern file.
