Patent number: 6947242Abstract: Disclosed is an apparatus and method for dynamic fly height and roll adjustment of a physical asperity sensor (PAS) head. The PAS head is used to test disk asperity heights and mechanical interference (commonly known as glide height and take off height). The PAS may be adjusted through a pivoting device such as a joystick coupled through one or more actuators to the pivoting device by actuator arms. In one embodiment, the actuator is a piezoelectric motor. The PAS head may utilize a detector to indicate the distance of the disk asperity from the PAS head. The method comprises receiving the signal and in response, operating the actuators to adjust the position of the pivoting device to obtain a selected positioning of either the fly height or the roll of the PAS.Type: GrantFiled: April 16, 2002Date of Patent: September 20, 2005Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Hong S. Seing, Bob C. Robinson, Ullal Vasant Nayak, Carl Robert Mendel, Wesley LeRoy Hillman, Tony Mello, Steven Harry Voss

Patent number: 6249959Abstract: A tool block holds an integrated lead suspension during assembly. The tool block has a number of features for precisely positioning the integrated lead suspension while transducer heads are being mechanically and electrically connected to it. The most critical feature is a movable datum clamping pin which is positioned to precisely engage a mount plate on the integrated lead suspension. Other features of the tool block include a platform support, a locating hole, a platform clamp and a pivot arm.Type: GrantFiled: January 3, 2000Date of Patent: June 26, 2001Assignee: International Business Machines CorporationInventors: Carl Robert Mendel, Darrick Taylor Smith, Dennis James Veerkamp, Steven Harry Voss

Patent number: 6088912Abstract: A clamp assembly holds an integrated lead suspension during assembly. The clamp assembly has a number of features for precisely positioning the integrated lead suspension while transducer heads are being mechanically and electrically connected to it. The clamp assembly works in conjunction with a stationary platform which restricts movement of the suspension in three directions. The clamp assembly includes upper and lower support plates which compensate for lateral misalignment, and a pair of clamps which independently isolate the suspension and slider while compensating for rotational misalignment.Type: GrantFiled: July 1, 1998Date of Patent: July 18, 2000Assignee: International Business Machines CorporationInventors: Edward Kou-Wei King, Darrick Taylor Smith, Steven Harry Voss

Patent number: 5986852Abstract: A low profile, high capacity, high performance disk drive includes a plurality of disk surfaces mounted in parallel for simultaneous rotation about an axis. Each of a plurality of data transducer heads for reading and/or writing data to the data surfaces is attached to a slider. A stacked arm actuator for moving the data transducer heads in a radial direction across the disk surfaces includes a supporting arm and a suspension load beam attached to the supporting arm. The suspension load beam connects the supporting arm to the slider. The suspension load beam includes a load dimple bearing on the slider and has opposed stiffening flanges extending in a plane adjacent the slider. The actuator includes a stack of 9 head arm suspension assemblies and the stack has a height of 16.634 mm. An interdisk spacing of less than 1.4 mm provides a height dimension of 14.635 for a stack of 8 disks.Type: GrantFiled: October 19, 1992Date of Patent: November 16, 1999Assignee: International Business Machines CorporationInventors: Lowell James Berg, William Woodrow Brooks, Jr., Jerome Thomas Coffey, Daniel Lee Good, Richard Greenberg, Peter Maurice Herman, John Charles Jans, Sr., Kenneth William Meyer, Jerry Lee Neubauer, John Ralph Reidenbach, Steven Harry Voss, Donald John Wanek, Walter Ervin Zahn

Patent number: 5892637Abstract: An integrated suspension for a slider in a magnetic storage system has a simplified structure that is relatively easy to manufacture. The novel integrated suspension may be assembled from separate pieces, including a load beam, a flexure and a mounting plate. The load beam provides rigid structural support of the flexure. The flexure includes a flexible member and leads integrally formed thereon. A section of the flexible member is fixedly attached to the load member, and another section having the slider mounted thereon presses against a pivot projection in the load beam for gimbal motions. An interlocking structure is provided to limit the extent of gimbal motions of the flexible member, comprising a tab extending from the flexible member into an aperture in the load beam. Alternatively, a tang is formed in the flexible member which is used to form a clip which serves to limit gimbal motions as it interacts with the load beam.Type: GrantFiled: May 10, 1996Date of Patent: April 6, 1999Assignee: International Business Machines CorporationInventors: William Woodrow Brooks, Jr., Wesley LeRoy Hillman, Darrell Dean Palmer, Randall George Simmons, Steven Harry Voss, Wing Chun Shum

Patent number: 5427309Abstract: A box is formed of a blank of sheet material wherein a filler is sandwiched between an inner liner and an outer liner. A pair of V-grooves is formed parallel to each edge and another V-groove is formed parallel to the pair of grooves on the side away from the edge. The V-grooves of the pair of V-grooves have center lines spaced apart a distance of substantially two thicknesses of the sheet material. The blank is folded upwards at the single V-groove, and then is folded back at the pair of V-grooves to produce successive 90-degree folds. The outer liner extends continuously over the outer side, top edge, and inner side of the resulting double-thickness wall. A similar technique can produce a box with multiple-thickness walls.Type: GrantFiled: October 28, 1994Date of Patent: June 27, 1995Assignee: Rock City Box Company, Inc.Inventor: Harry A. Voss

Patent number: 5337916Abstract: A box is formed of a blank of sheet material wherein a filler is sandwiched between an inner liner and an outer liner. A dado groove is formed parallel to each edge and a V-groove is formed parallel to the dado groove on the side away from the edge. The blank is folded up at the V-groove and then is folded back at the dado to produce a 180 degree fold. The outer liner extends continuously over the outside, top edge, and inner side of the resulting double thickness wall.Type: GrantFiled: October 4, 1993Date of Patent: August 16, 1994Assignee: Rock City Box CompanyInventor: Harry A.
