Patent number: 11200911Abstract: A data storage device is disclosed comprising a head actuated over a magnetic media comprising a plurality of data tracks, wherein each data track comprises a plurality of data sectors. A first codeword is encoded, and the first codeword is written to multiple data sectors of a first data track including a first data sector. A second codeword is encoded, and at least part of the second codeword to is written to the multiple data sectors of a second data track adjacent the first data track including a second data sector adjacent the first data sector of the first data track. The first codeword is partially written to at least the first data sector of the first data track when the first data sector of the first data track is corrupted by writing the second codeword to the second data track.Type: GrantFiled: February 15, 2021Date of Patent: December 14, 2021Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Scott E. Burton, Gregory B. Thelin, Steven Vasquez

Patent number: 10910011Abstract: A data storage device is disclosed comprising a head actuated over a disk. The disk is spun at a first speed while writing first data to the disk based on a first disk format defining a first capacity for the disk. When a command is received from a host to spin the disk at a second speed different from the first speed, the disk is spun at the second speed while writing second data to the disk based on a second disk format defining a second capacity for the disk different from the first capacity.Type: GrantFiled: January 30, 2020Date of Patent: February 2, 2021Assignee: Western Digital Technologies, Inc.Inventors: Curtis A. Harper, Paul E. Movall, Scott E. Burton, David R. Hall

Publication number: 20180189183Abstract: A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks, wherein each track comprises a plurality of data sectors comprising a disk block size. A host write command is received comprising data blocks having a host block size less than the disk block size. A misalignment is detected between the data blocks and the disk block size, and when the misalignment is detected, at least one of the data blocks is stored in a write cache. A command rate limit is adjusted as a function of the write cache, wherein the command rate limit defines a limit on a number of commands received from a host.Type: ApplicationFiled: February 27, 2018Publication date: July 5, 2018Inventors: Scott E. Burton, Kenny T. Coker, Robert M. Fallone

Patent number: 9959209Abstract: A data storage device is disclosed comprising a non-volatile memory. A command rate profile is initialized, wherein the command rate profile defines a limit on a number of access commands received from a host as a function of an internal parameter of the data storage device. The command rate profile is adjusted in response to a change in operating mode.Type: GrantFiled: March 23, 2010Date of Patent: May 1, 2018Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Scott E. Burton, Kenny T. Coker, Robert M. Fallone

Patent number: 9870281Abstract: A Data Storage Device (DSD) includes a disk for storing data, a volatile memory for temporarily storing data to be written on the disk, and a Non-Volatile Solid-State Memory (NVSM) for storing data. Data is stored in the volatile memory in preparation for writing the data on the disk. The data is written from the volatile memory onto the disk, and it is determined whether the data written on the disk is qualified as written. In the event of an unexpected power loss, a portion of unqualified data that has not been qualified as written is transferred from the volatile memory to the NVSM.Type: GrantFiled: March 20, 2015Date of Patent: January 16, 2018Assignee: Western Digital Technologies, Inc.Inventors: Asif F. Gosla, Scott E. Burton, Chiranjeb Mondal

Patent number: 9842622Abstract: Systems and methods for improving read failure tolerance during read-modify-write operations of data storage systems accommodating a host that uses a logical sector of a size smaller than the physical sector size of the data storage system. In one embodiment, the data storage system can perform sector indirection in response to a read error during a read-modify-write command.Type: GrantFiled: December 23, 2014Date of Patent: December 12, 2017Assignee: Western Digital Technologies, Inc.Inventors: Albert Monroe, Scott E. Burton

Patent number: 8898379Abstract: A control arrangement, for example, in a digital component that forms part of a system, draws an input current for its operation and is configured for monitoring an interface for any one of a group of commands and, upon detecting an issued one of the group of commands, operates the component for executing the issued command in an operational mode, and during an idle time on the interface, the control arrangement exclusively monitors the interface for any one of the group of commands such that the input current is limited to a leakage current. The component may draw less than 1 milliamp of current during the idle mode.Type: GrantFiled: December 27, 2012Date of Patent: November 25, 2014Assignee: Benhov GmbH, LLCInventors: Christopher J. Squires, Scott E. Burton, Douglas I. McCampbell, Larry J. Koudele, George C. Cope, James B. French, Jr.

Patent number: 8797669Abstract: A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of data tracks, wherein each data track comprises a plurality of data sectors. A host write command is received from a host, and previous data is read from at least one data sector which is combined with at least one of the host blocks to generate modified data that is written to the at least one data sector. At least one of a first read command and a first write command is generated, wherein the first read command is for reading the previous data from and the first write command is for writing the modified data to the at least one data sector. At least one of the first read command and the first write command is stored in a command queue for execution based on a rotational position optimization (RPO) algorithm.Type: GrantFiled: September 30, 2013Date of Patent: August 5, 2014Assignee: Western Digital Technologies, Inc.Inventor: Scott E. Burton

Patent number: 8578242Abstract: A data storage device is disclosed including a non-volatile memory comprising a plurality of memory segments. The LBAs of a read command are mapped to PBAs addressing the memory segments. At least two seed values corresponding to two of the LBAs are generated and stored in an array. The array is then indexed to access the seed value corresponding to each LBA, wherein the seed value is used to seed an error code generator.Type: GrantFiled: January 29, 2010Date of Patent: November 5, 2013Assignee: Western Digital Technologies, Inc.Inventors: Scott E. Burton, Michael C. Kutas
