Appl. No.:

13/626846

Inventors:

Jian Yang - Fremont CA, US
Qiang Yang - Fremont CA, US

Assignee:

Method For Fine Actuation Of A Head During Operation Of A Disk Drive

View page

US Patent:

8593764, Nov 26, 2013

Filed:

Nov 8, 2012

Appl. No.:

13/672636

Inventors:

Qiang Yang - Fremont CA, US
Jian Yang - Fremont CA, US

Assignee:

Western Digital Technologies, Inc. - Irvine CA

International Classification:

G11B 5/127

US Classification:

3602454

Abstract:

A disk drive includes a voice coil actuator, and a rotary fine actuator that is attached to the head mounting tongue of the flexure of a suspension assembly. The head is positioned during operation of the disk drive by a novel method. An electrical current is driven through a coil of the voice coil actuator to torque it towards a desired coarse position. First and second voltages are applied across first and second piezoelectric elements attached to the flexure, respectively. The first and second voltages cause longitudinal deformation of the first and second piezoelectric elements, respectively, the longitudinal deformation consisting of expansion relative to a zero-voltage state. The first and second voltages do not switch polarity during normal operation of the first and second piezoelectric elements.

Disk Drive Actuator Having A Bobbin Contacting A Closed Coil Periphery At Two Locations

View page

US Patent:

8125740, Feb 28, 2012

Filed:

May 11, 2010

Appl. No.:

12/778033

Inventors:

Jian Yang - Fremont CA, US
Jifang Tian - Fremont CA, US
Qiang Yang - Fremont CA, US
Hongqi Li - Redwood City CA, US

Assignee:

Western Digital Technologies, Inc. - Irvine CA

International Classification:

G11B 21/02

US Classification:

3602658

Abstract:

A disk drive has an actuator coil that includes first and second lateral legs joined by first and second longitudinal legs to form a closed coil periphery. The first lateral leg is disposed closer to the actuator pivot bore than the second lateral leg. The first and second longitudinal legs join the second lateral leg at a first interior bend location and at a second interior bend location within the closed coil periphery, respectively. A bobbin is disposed within the closed coil periphery and contacts the conductive coil at two locations (e. g. the first interior bend location and the second interior bend location). Preferably, the bobbin defines a total bobbin length and an average bobbin width, and the total bobbin length is at least 3 times the average bobbin width.

G02B 27/64
G02B 7/08
G02B 7/10
H04N 5/225
G02B 7/09

Abstract:

Various embodiments include a damper arrangement that may be used to dampen motions of a dynamic component. In some embodiments, the damper arrangement may be used in a camera module that includes a stationary component and a dynamic component. For instance, the dynamic component may hold a lens such that the lens moves together with the dynamic component. In various examples, the damper arrangement may include an interface member that extends from the stationary component or the dynamic component to at least partially into a viscoelastic material within a pocket configured in the stationary component, the dynamic component, or both. The interface member may be configured to traverse within the viscoelastic material to dampen motion of the dynamic component, for example, during operation of a lens actuator to move the dynamic component along an optical axis of the lens.
