Filed:

Mar 12, 2002

Appl. No.:

10/096704

Inventors:

Brett T. Holaway - Cosmos MN
Mark A. Miller - Hutchinson MN
Eric O. Naatz - Hutchinson MN

Assignee:

Hutchinson Technology Incorporated - Hutchinson MN

International Classification:

G11B 5596

US Classification:

3602452, 3602454

Abstract:

A head suspension for supporting a head slider over a rigid disk in a dynamic storage device having a component that includes a compliant feature adapted to engage a first pin and a datum engaging surface spaced from the compliant feature. The component being locatable relative to a datum by manipulation of the component with respect to the datum and a first pin to cause the first pin to engage and deflect the compliant feature when the datum engaging surface of the component is engaged and positioned with respect to the datum. The head suspension also including a second component having a pin engaging feature and possibly a datum engaging surface alignable with the compliant feature and datum engaging surface of the first component, respectively. The pin engaging feature of the second component being compliant or non-compliant. The compliant and non-compliant features being usable for locating head suspension components, such as load beams, flexures, and base plates, relative to each other or to tooling for head suspension fabrication purposes.

International Classification:

B08B 6/00

US Classification:

134 1, 3602454, 3602453, 360255

Abstract:

A method of cleaning an contaminated surface on a head suspension with laser energy. A laser beam is patterned such that a single pulse extends across the entire contaminated surface. One or more pulses of the laser energy is applied to the contaminated surface sufficient to melt the contaminated surface. The melting serves to polish, smooth and/or reshape the contaminated surface.

Brett Holaway - Temecula CA, US

Assignee:

Magnecomp Corporation - Murrieta CA

International Classification:

H01L 29/84
G11B 5/48

US Classification:

257415, 360 7716, 360 81, 360104, 3602446, 257E27006

Abstract:

A test assembly for a disk drive suspension head gimbal assembly includes a steel mount plate and a mount sub-plate of a material such as silicon carbide having a modulus of elasticity to density ratio that is significantly higher than the ratio for stainless steel. Preferably the mount plate and the mount sub-plate taken together have a first resonant shear frequency of greater than 50 KHz, which is generally greater than the frequency range of interest for testing head gimbal assemblies. The high modulus of elasticity to density ratio helps to ensure that any shear mode resonances of the test assembly occur at frequencies that are higher than the frequencies of interesting for head gimbal assembly shear resonance testing purposes.
