Abstract
Official abstract text for this publication.
Examples of a head stack assembly arm are described herein. The head stack assembly arm includes a load beam in an upper nesting configuration including a lift tab with an inner edge. The head stack assembly arm includes a load beam in a lower nesting configuration including a lift tab with an inner edge, the inner edge of the load beam in the lower nesting configuration is a different size from the inner edge of the load beam in the upper nesting configuration.
First claim
Opening claim text (preview).
We claim: 1 . A head stack assembly arm comprising: a load beam in an upper nesting configuration including a lift tab with an inner edge; a load beam in a lower nesting configuration including a lift tab with an inner edge, the inner edge of the load beam in lower nesting configuration is a different size from the inner edge of load beam in the upper nesting configuration; and the load beam in the upper nesting configuration and the load beam in the lower nesting configuration are coupled with a rigid anchor arm. 2 . The head stack assembly arm of claim 1 , wherein the load beam in the lower nesting configuration is coupled with rigid anchor arm through a first base plate. 3 . The head stack assembly arm of claim 2 , wherein the load beam in the lower nesting configuration includes a slider connected to the load beam at the distal end via a flexure. 4 . The head stack assembly arm of claim 2 , wherein the load beam in the lower nesting configuration includes a pair of side rails configured to have a predetermined rigidity and load support capacity. 5 . The head stack assembly arm of claim 1 , wherein the load beam in the upper nesting configuration is coupled with rigid anchor arm through a second base plate. 6 . The head stack assembly arm of claim 5 , wherein the load beam in the upper nesting configuration includes a slider connected to the load beam at the distal end via a flexure. 7 . The head stack assembly arm of claim 5 , wherein the load beam in the upper nesting configuration includes a pair of side rails configured to have a predetermined rigidity and load support capacity. 8 . The head stack assembly arm of claim 1 , wherein the lift tab of the load beam in the upper nesting configuration is formed with a smaller lift tab width than the lift tab of the load beam in the lower nesting configuration. 9 . The head stack assembly arm of claim 1 , wherein the lift tab of the load beam in the upper nesting configuration is formed with a larger lift tab width than the lift tab of the load beam in the lower nesting configuration. 10 . The head stack assembly arm of claim 1 , wherein the lift tab of the load beam in the upper nesting configuration is configured to have a width larger than the lift tab of the load beam in a lower nesting configuration, the lift tab of the load beam in the upper nesting and the load beam in the lower nesting configuration are configured to nest with each other.
