Method and system for adjustment of components in a head stack assembly
First Claim
1. A method of measuring and adjusting at least one of a plurality of head suspension assemblies in a head stack assembly, each head suspension assembly having a pivot axis, the method comprising the steps of:
- stacking a plurality of head suspension assemblies in a head stack assembly so that the pivot axis of each head suspension assembly is aligned with the pivot axis of at least one adjacent head suspension assembly, wherein at least one of the head suspension assemblies is rotated about its pivot axis relative to at least one adjacent head suspension assembly so that all of the plurality of head suspension assemblies are not in vertical alignment within the head stack assembly;
measuring at least one parameter of at least one head suspension assembly;
rotating each of the plurality of head suspension assemblies that is not in vertical alignment with the other head suspension assemblies about its pivot axis until the plurality of head suspension assemblies are vertically aligned within the head stack assembly.

Abstract
A method of measuring and adjusting at least one of a plurality of head suspension assemblies in a head stack assembly is provided, each head suspension assembly having a pivot axis, comprising the steps of stacking a plurality of head suspension assemblies with the pivot axis of each head suspension assembly aligned with the pivot axis of at least one adjacent head suspension assembly, wherein at least one of the head suspension assemblies is rotated about its pivot axis relative to at least one adjacent head suspension assembly so that all of the plurality of head suspension assemblies are not in vertical alignment, measuring at least one parameter of at least one head suspension assembly, then rotating each of the plurality of head suspension assemblies that are not in vertical alignment with the other head suspension assemblies about its pivot axis until the plurality of head suspension assemblies are vertically aligned.

- 21. A head suspension measuring and adjusting system for measuring and adjusting at least one parameter of each of a plurality of head suspension assemblies arranged in a head stack assembly, the system comprising a head stack assembly comprising a plurality of head suspension assemblies, wherein each head suspension assembly comprises a pivot axis that is aligned with the pivot axis of at least one adjacent head suspension assembly, and wherein each of the head suspension assemblies is rotatable about its pivot axis to be misaligned with the other head suspension assemblies within the head stack assembly and further rotatable about its pivot axis to be aligned with at least one of the other head suspension assemblies within the head stack assembly.
