Controlling Seeks Using Non-Linear Switching Curves

View page
US Patent:
7580219, Aug 25, 2009
Filed:
Feb 21, 2007
Appl. No.:
11/708817
Inventors:
Jeffrey V. Derosa - Burlington MA, US
Orhan Beker - Aliso Viejo CA, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 5/55
US Classification:
360 7806, 360 7807, 360 7814
Abstract:
Controlling seeking of a transducer includes accelerating the transducer to a seek velocity, generating a linearized switching curve defining a position and velocity of the transducer at which deceleration should begin, and controlling the velocity of the transducer in response to the current position and seek velocity of the transducer relative to the linearized switching curve. The linearized switching curve has a slope and an offset that are determined in response to the seek velocity and a current position of the transducer relative to a nonlinear switching curve.

Disk Drive Employing Data-Based Basis Function Expansion For Tuning Seek Servo Loop

View page
US Patent:
7839600, Nov 23, 2010
Filed:
May 4, 2009
Appl. No.:
12/434979
Inventors:
Alexander Babinski - Laguna Niguel CA, US
Orhan Beker - Aliso Viejo CA, US
Duc T. Phan - Saratoga CA, US
Assignee:
Western Digital Technologies, Inc. - Lake Forest CA
International Classification:
G11B 5/596
US Classification:
360 7806, 360 7804, 360 7814
Abstract:
A method of tuning a seek operation of a disk drive is disclosed, the disk drive comprising a disk, an actuator arm, a head coupled to a distal end of the actuator arm, a voice coil motor (VCM) for rotating the actuator arm about a pivot, and a closed loop servo system for generating a VCM control signal applied to the VCM. A function h is applied to the closed loop servo system and a corresponding output g of the closed loop servo system is measured. A reference signal is generated in response to a summation of a plurality of the function h, wherein each of the plurality of the function h is shifted by an offset and scaled by a coefficient, and the coefficients are generated in response to the measured output g.

Disk Drive Choosing Command From Command Queue Based On A Window Defined By A Probability Of A Seek Miss

View page
US Patent:
8498074, Jul 30, 2013
Filed:
Aug 18, 2011
Appl. No.:
13/212901
Inventors:
Jack A. Mobley - Oklahoma City OK, US
Kenny T. Coker - Firestone CO, US
Orhan Beker - Aliso Viejo CA, US
Assignee:
Western Digital Technologies, Inc. - Irvine CA
International Classification:
G11B 5/02
G06F 13/00
G06F 13/28
US Classification:
360 55, 711112, 711158
Abstract:
A disk drive is disclosed wherein a plurality of access commands received from a host are stored in a command queue. An access cost for at least a first and second access command in the command queue is generated, wherein each access cost comprises a seek length and a rotation latency. A first access command is selected from the command queue having a first access cost, and a window is defined relative to the first access cost and a first risk based penalty (RBP) of the first access command, wherein the first RBP represents a probability of missing a first data sector of the first access command. A second access command is selected from the command queue comprising a second access cost within the window. A choice is made between the first and second access commands in response to a second RBP of the second access command.

Disk Drive Employing System Inversion For Tuning Seek To Settle Servo Loop

View page
US Patent:
8508881, Aug 13, 2013
Filed:
May 26, 2011
Appl. No.:
13/117036
Inventors:
Alexander Babinski - Laguna Niguel CA, US
Orhan Beker - Aliso Viejo CA, US
Duc T. Phan - Saratoga CA, US
Donald Brunnett - Pleasanton CA, US
Assignee:
Western Digital Technologies, Inc. - Irvine CA
International Classification:
G11B 5/596
US Classification:
360 7804, 360 7806
Abstract:
A method is disclosed of operating a disk drive, the disk drive comprising a disk having a plurality of tracks, a head, and a closed loop servo system comprising a seek servo loop and a settle servo loop for actuating the head over the disk. The seek servo loop is used to seek the head toward a target track. When the head approaches the target track, the settle servo loop is used to settle the head on the target track in response to a reference signal generated in response to a system inversion of the settle servo loop.

Appl. No.:
13/206354
Inventors:
Mingji Lou - Corona CA, US
Xiuli Guo - Irvine CA, US
Orhan Beker - Aliso Viejo CA, US
Assignee:
Western Digital Technologies, Inc. - Irvine CA
International Classification:
G11B 5/596
US Classification:
360 7806
Abstract:
A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks, and control circuitry operable to seek the head to a target track and settle the head on the target track during a settle time, adapt a settle parameter used to settle the head on the target track, access the target track after an access delay, and decrease the access delay based on a speed that the settle parameter adapts.

Disk Drive That Compensates For Track Radial Pitch Variation And Methods Thereof

View page
US Patent:
20070097806, May 3, 2007
Filed:
Aug 8, 2006
Appl. No.:
11/500691
Inventors:
Orhan Beker - Rancho Santa Margarita CA, US
Bernie Rub - Sudbury MA, US
John Hawk - Shrewsbury MA, US
International Classification:
G11B 21/08
US Classification:
369030120
Abstract:
A disk drive includes a rotatable data storage disk having a plurality of radially distributed tracks, and where radial pitch between at least some of the tracks varies across the disk. A head is configured to read/write data on the tracks. An actuator is configured to position the head relative to the disk. A controller is configured to respond to a host read/write command identifying a track address on the disk by determining a corresponding shifted radial location on the disk that is radially offset from an actual location of the addressed track by a distance that at least partially compensates for the radial pitch variation between at least some of the tracks on the disk. Corresponding methods are disclosed for positioning a head that is adjacent to a rotatable disk in a disk drive so as to at least partially compensate for radial pitch variation between at least some of the tracks on the disk.

Method And Apparatus For Reducing Off-Track Writes In Data Storage Devices

View page
US Patent:
7224543, May 29, 2007
Filed:
Jun 4, 2004
Appl. No.:
10/861101
Inventors:
Mirmehdi L. Abrishamchian - Shrewsbury MA, US
Orhan Beker - Shrewsbury MA, US
Kevin Blankespoor - Framingham MA, US
Assignee:
Maxtor Corporation - Scotts Valley CA
International Classification:
G11B 15/04
US Classification:
360 60
Abstract:
The present invention is directed to a method and apparatus for reducing off-track writes in a data storage device. In one embodiment, a command is received to perform a write operation using a write head at a first location on a disk surface. A determination is made as to whether to perform or inhibit the write operation using an equation having a tunable acceleration coefficient. The equation is used to predict a position error signal (PES) value for a write head at a servo sector that immediately circumferentially follows the first location (i. e. , there are no intervening servo sectors between the servo sector and the first location). If the predicted PES value is outside of (e. g. , greater than or less than) a predetermined threshold, an off-track write is likely to occur and the write operation is inhibited.
