Appl. No.:

09/283840

Inventors:

Kochan Ju - Fremont CA
Po-Kang Wang - San Jose CA
Chun Liu - Fremont CA

Assignee:

Headway Technologies, Inc. - Milpitas CA

International Classification:

H04R 3100

US Classification:

2960314, 2960315

Abstract:

A merged read/write magnetic recording head comprises a low magnetic moment first magnetic shield layer over a substrate. A read gap layer with a magnetoresistive head is formed over the first shield layer. A shared pole comprises a low magnetic moment second magnetic shield layer plated on a sputtered seed PLM layer over the read gap layer, a non-magnetic layer plated over the PLM layer and a HMM lower pole layer plated over the second magnetic shield layer. A write gap layer is formed over the first high magnetic moment pole layer of the shared pole. An upper pole comprises a high magnetic moment pole layer over the write gap layer.

Abstract:

A method of manufacturing a magnetic recording head includes the following steps. Form a low magnetic moment, first magnetic shield layer over a substrate. Form a read gap layer with a magnetoresistive head over the first shield layer. Form a seed layer over the read gap layer covered with a frame mask with a width âFâ. Form a PLM second shield layer over the seed layer and planarize the shield layer. Form a non-magnetic copper or dielectric spacer layer over the PLM second shield layer. Form a first HMM, lower pole layer over the non-magnetic spacer layer. Cover the first HMM, lower pole layer with a write gap layer. Form an write head mask composed of two parallel rows of resist with an outer width âWâ over the seed layer. Between the two rows of resist of the write head mask is a trench having a width âNâ. Then form an HMM, upper pole layer over the write gap layer aside from the write head mask.

International Classification:

G06F 1750

US Classification:

364491

Abstract:

A method for producing a circuit layout comprising the steps of establishing high-level input parameters which identify input/output characteristics and high-level functional parameters of a data path, inputting the input parameters to a compiler, the compiler performing steps of creating a data path netlist by selecting data path components in response to the established high-level input parameters; and automatically selecting control logic for the data path components. The data path netlist is a high-level netlist of Boolean logic which can then easily be translated into a gate level implementation of the circuit layout.

International Classification:

G06F 3/06

Abstract:

A data reading method, apparatus, and system, and a distributed system, related to the field of storage technologies and can be applied to data reading. The method includes: receiving a data read request sent by a terminal, where the data read request includes a logical address of target data; locally searching, based on the logical address, a first slave node for a latest version of the target data; and, when it is determined that the latest version of the target data has been stored in each of a plurality of slave nodes, sending the latest version of the target data to the terminal. This data reading method, apparatus, system, and distributed system can avoid a rollback of a version of read data.
