7209310, Apr 24, 2007
Filed:

Jul 25, 2005
Appl. No.:

11/188947
Inventors:

Chun Sei Tsai - Tustin CA, US
Ngoc Le - Fountain Valley CA, US
Jenghung Chen - Cupertino CA, US
Hien Chu - Santa Ana CA, US
Assignee:

Western Digital Technologies, Inc. - Lake Forest CA
International Classification:

G11B 21/02
US Classification:

360 75, 360 7808
Abstract:

A disk drive is disclosed comprising a disk having a plurality of servo sectors defining a plurality of servo tracks, wherein each servo sector comprises a track address identifying a corresponding servo track. A head is actuated over the disk, and a ramp is positioned near an outer diameter of the disk, wherein an edge of the ramp extends over a plurality of the servo tracks. The head is loaded from the ramp onto the disk, and a track address in at least one of the servo sectors is detected and stored. The process is repeated a number of times, and then a starting track proximate an outer diameter of the disk is identified in response to the detected and stored track addresses.

Mar 27, 2009
Appl. No.:

12/413408
Inventors:

William B. Boyle - Lake Forest CA, US
Chun Sei Tsai - Tustin CA, US
Anthony L. Pei - Irvine CA, US
Assignee:

Western Digital Technologies, Inc. - Irvine CA
International Classification:

G11B 27/36
US Classification:

360 31, 360 53
Abstract:

A disk drive is disclosed comprising a head actuated over a disk, the disk having a plurality of data tracks, wherein a first plurality of data tracks comprises a first plurality of defect scanned data sectors and a second plurality of data tracks comprises a second plurality of unscanned data sectors. The second plurality of data tracks is divided into a plurality of defect zones. A first number of write commands are received from a host to write data to a first defect zone. A first data sector in the first defect zone is defect scanned in response to the first number of write commands to the first defect zone.

Disk Drive Storing Parameters Of A Write Operation In A Plurality Of Data Sectors

US Patent:

7933087, Apr 26, 2011
Filed:

Jun 18, 2008
Appl. No.:

12/141693
Inventors:

Chun Sei Tsai - Tustin CA, US
William B. Boyle - Lake Forest CA, US
Carl E. Barlow - Lake Forest CA, US
Assignee:

Western Digital Technologies, Inc. - Irvine CA
International Classification:

G11B 5/09
US Classification:

360 48
Abstract:

A disk drive is disclosed comprising a disk having a plurality of data sectors, and a head actuated over the disk. The disk drive further comprises control circuitry operable to execute a write operation for writing data to the disk. A first part of the data is written to a first data sector together with a first sector signature data (SSD) record comprising a first parameter of the write operation and a first id that identifies the first parameter. A second part of the data is written to a second data sector together with a second SSD record comprising a second parameter of the write operation and a second id that identifies the second parameter.

Disk Drive Refreshing Zones In Segments To Sustain Target Throughput Of Host Commands
view source
US Patent:

7945727, May 17, 2011
Filed:

Jul 27, 2007
Appl. No.:

11/829819
Inventors:

Michael S. Rothberg - Foothill Ranch CA, US
William B. Boyle - Lake Forest CA, US
Chun Sei Tsai - Tustin CA, US
Assignee:

Western Digital Technologies, Inc. - Irvine CA
International Classification:

G06F 12/00
US Classification:

711112, 711106, 711167, 710 45, 710 58
Abstract:

A disk drive is disclosed including a disk comprising a plurality of refresh zones, and a head actuated over the disk. The disk drive further comprises control circuitry for receiving access commands from a host. The control circuitry refreshes a refresh zone in a plurality of segments with an interval between each segment, and processes at least one of the access commands during the interval between at least two of the segments, wherein a size of each segment and the interval ensures an average throughput of access commands received from the host does not fall below a first threshold.

US Patent:

8004785, Aug 23, 2011
Filed:

May 9, 2008
Appl. No.:

12/118365
Inventors:

Chun Sei Tsai - Tustin CA, US
William B. Boyle - Lake Forest CA, US
Carl E. Barlow - Lake Forest CA, US
Kenneth J. Smith - Corona CA, US
Assignee:

Western Digital Technologies, Inc. - Irvine CA
International Classification:

G11B 5/09
US Classification:

360 53
Abstract:

A disk drive is disclosed comprising a disk having a plurality of data sectors, wherein a physical block address (PBA) is associated with each data sector. When a write command is received from a host to write user data to the disk, and the write command comprises an unformatted logical block address (LBA), the user data is written to a first data sector, and the first data sector is write verified. A second data sector is defect scanned, and after the second data sector passes the defect scan, the user data is migrated from the first data sector to the second data sector and the LBA is formatted to the second data sector.
