Suspension Interconnect With Controlled Noise

View page
US Patent:
6975488, Dec 13, 2005
Filed:
May 29, 2002
Appl. No.:
10/159418
Inventors:
Sivadasan Kulangara - Temecula CA, US
Amanullah Khan - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
G11B005/48
US Classification:
360246
Abstract:
A disk drive suspension and method has a metal load beam and an electrical interconnect assembly. The interconnect assembly has an insulative layer, a read pair of forward and return path conductive traces, a write pair of forward and return path conductive traces that are supported by the insulative layer, preferably in offset relation across the insulative layer, and a metal layer for grounding and mounted on the insulative plastic layer in fixed spaced relation to the conductive traces to be between the interconnect assembly and the load beam. The metal layer shields the conductive traces from variations in impedance occasioned by varying distances between said electrical interconnect and said load beam.

Hga Dynamics Testing With Shear Mode Piezo Transducers

View page
US Patent:
7034372, Apr 25, 2006
Filed:
Aug 31, 2004
Appl. No.:
10/930918
Inventors:
Sivadasan Kulangara - Temecula CA, US
Amanullah Khan - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
H01L 29/84
US Classification:
257415, 257E27006
Abstract:
An HGA dynamics tester and method are provided in which a shear mode piezo actuator having a dimensional change responsive to an input voltage while supported on a mass is coupled through an HGA support to impart movement to the HGA responsive to the actuator dimensional change.

Flexible Circuit Laminate Shunt For Disk Drive Suspensions

View page
US Patent:
7035050, Apr 25, 2006
Filed:
Jul 2, 2002
Appl. No.:
10/189884
Inventors:
Sivadasan Kulangara - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
G11B 5/48
US Classification:
3602459, 360323
Abstract:
A disk drive suspension interconnect of a flexible conductive laminate with an electrically insulative layer and a pair of trace conductors supported thereon is shunted by having an insulative layer first portion supporting the trace conductors oppose a deflectable layer second portion free of the trace conductors and disposed beyond the first portion and carrying a shunt structure for connecting in parallel the trace conductors. The shunt structure conductive material is arranged on the second portion to contact in shunting relation the trace conductor pair in the deflected condition of the second portion and further has adhesive arranged thereon to secure the first portion in place.

Additive-Process Suspension Interconnect With Controlled Noise

View page
US Patent:
7079357, Jul 18, 2006
Filed:
Nov 7, 2005
Appl. No.:
11/268986
Inventors:
Sivadasan Kulangara - Temecula CA, US
Amanullah Khan - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
G11B 5/48
US Classification:
3602459
Abstract:
A disk drive electrical interconnect assembly and additive method therefor. The interconnect assembly has a supporting or fifth layer of metal, a fourth layer of a polyimide precursor or a polyimide with a first face directed away from the fifth layer, a third layer directly attached to the first face and defining a first subset of one or more conductive trace pair members, a second layer on the third and fourth layers of a polyimide precursor or a polyimide with a second face directed away from the third layer, and a first layer directly attached to the second layer and defining a second subset of one or more conductive trace pair members in spaced, paired and laterally offset relation respectively with one or more of the first subset pair members.

Head Gimbal Assembly With Dual-Mode Piezo Microactuator

View page
US Patent:
7417830, Aug 26, 2008
Filed:
Oct 28, 2005
Appl. No.:
11/260990
Inventors:
Sivadasan Kulangara - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
G11B 5/56
G11B 5/596
US Classification:
3602944, 3602445
Abstract:
A disk drive suspension has a load beam having a base, a flexure for carrying a slider, and a mount plate. The suspension mount plate has a first portion attachable to an actuator and movable by the actuator as the primary shifting force on the load beam, suitable for larger positioning movements. A second portion of the mount plate is attached to the load beam base and is movable relative to the mount plate first portion. A microactuator moves the second mount plate portion relative to the first mount plate portion as a secondary shifting force on the load beam, suitable for very small positioning movements.

Single Pzt Actuator For Effecting Rotation Of Head Suspension Loads

View page
US Patent:
7595965, Sep 29, 2009
Filed:
Nov 18, 2005
Appl. No.:
11/282305
Inventors:
Sivadasan K. Kulangara - Murrieta CA, US
Shijin Mei - Murrieta CA, US
Steve Misuta - Temecula CA, US
Chris Schreiber - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
G11B 5/56
US Classification:
3602946
Abstract:
A head suspension assembly couples a baseplate to a rotatable load through a planar triangular piezo microactuator for effecting hingeless rotation of the load. The microactuator expands, responsive to an excitation voltage, with greater magnitude in one direction than in another direction normal to the first direction, resulting in an angular movement of the hypotenuse thereby rotating the load. The upper surface of the microactuator is grounded to a bottom surface of the baseplate or load beam to position the microactuator lead connection surface closest to the load to facilitate trace routing. A load beam grounding surface may be raised to accommodate the microactuator and fix the lead connection surface on a common plane with the unraised surface to further minimize trace routing and provide access for bonding the trace to the load beam.

Suspension Shock Characteristic Test Method And Apparatus

View page
US Patent:
6910365, Jun 28, 2005
Filed:
Dec 8, 2003
Appl. No.:
10/730176
Inventors:
Sivadasan Kulangara - Temecula CA, US
Amanullah Khan - Temecula CA, US
Assignee:
Magnecomp Corporation - Temecula CA
International Classification:
G01P015/00
US Classification:
73 1201
Abstract:
An apparatus and method for determining the shock characteristic of a suspension having a proximate portion, a distal portion and a spring portion therebetween has a rotatable structure having a mount for the suspension base portion such that the suspension distal portion is cantilevered over the rotatable structure, and a sensor carried on the rotatable structure for sensing the displacement of the suspension distal portion relative to the suspension proximate portion under shock load from centrifugal force imparted to the suspension by the rotatable structure. The shock characteristic value is determinable from the displacement value.
