Patent ID: 7667931

Claim:
In a disk drive including a disk supported for rotation thereof, an apparatus comprising: a head stack assembly including first and second portions, at least generally opposing one another, with a hub therebetween at least for pivotally supporting the first portion using a pivot arrangement and having a side margin that includes a circular configuration that is concentric with a center of rotation of the head stack assembly, said second portion is pivotally supported by said pivot arrangement for pivotal movement with said first portion, said first portion supports a coil, and said second portion supports a transducer arrangement for performing a data access using said disk; a flexible electrical interconnection arrangement having a length that extends between a first end and a second end, said first end being attached for rotation with the head stack assembly, said second end being attached to a given position in the disk drive for use in making a plurality of external electrical connections for said transducer arrangement and said coil, and a first portion of said flexible electrical interconnection arrangement, proximate to said first end, wherein said first portion urges against the side margin of said hub such that a rotation of the head stack assembly causes a length of said first portion to change over a given range of rotational movement of the head stack assembly; and a support wall for supporting a second portion of the flexible interconnection arrangement proximate to said second end, wherein said support wall also includes said circular configuration, concentric with said side margin of the hub in a radially spaced apart relationship therewith such that rotation of the head stack assembly changes a length of said second portion of the flexible interconnection arrangement which urges against the support wall.
