ABSTRACT:
A head stack assembly of a disk drive has a hub including a side margin defining a channel for carrying VCM conductors at least partially around an angular offset such that the conductors are contained within a peripheral outline of the hub and the conductors can extend completely within an overmolding thickness. A first portion of a flexible interconnection biases against a side margin of the hub such that a rotation of the HSA causes a length of the first portion to change. A floating portion of length of the flexible extension follows a semicircular path between a first contact position on the hub and a second contact position on the support surface such that a floating loop diameter is defined between the contact positions. The hub and the support surface can be configured for changing the floating loop diameter with rotation to vary resilient biasing torque to the HSA.
