Abstract

Embodied in this disclosure is a single piece actuator comb that provides arms with slots for aligning and bonding planar suspensions, or high volumetric densities (8+ disks, 14 + heads in a 2.5 form factor) with low assembly cost. This concept also improves performance (TPI, latency) by reducing the head skew.

In-Line Rotary Actuator for Low Profile Planar Suspension

      Embodied in this disclosure is a single piece actuator comb
that provides arms with slots for aligning and bonding planar
suspensions, or high volumetric densities (8+ disks, 14 + heads in a
2.5 form factor) with low assembly cost.  This concept also improves
performance (TPI, latency) by reducing the head skew.

      This actuator concept capitalizes on the potential of the
planar suspension for planar termination.  This concept is also
applicable to any other low profile suspension, but may not be as
adaptable for planar termination, without the planar suspension.  The
actuator design also provides the capability to minimize the amount
of head skew that results naturally from a rotary in-line actuator.
This is accomplished through the relationship of pivot to disk
centers, distance of head to pivot and track diameters.
