is said to enable the microactuator to operate at a resonant
frequency many times higher than the servo frequency with springs
that are relatively less stiff than those that would be utilized
if the entire slider were actuated.
Representative independent claim 1 is reproduced as follows:
1. A disc drive data storage system, comprising:
a disc mounted to a motor for rotating the disc about
an axis, the disc having a surface for storing
data thereon;
an access arm having a proximal end and a distal end;
a slider connected to the distal end of the access arm
and disposed adjacent the disc surface;
a comb microactuator mounted on the slider, the
microactuator including a stator portion having
fingers and a rotor portion having fingers
interdigitated with the fingers on the stator
portion; and
a transducer mounted on the rotor portion of the
microactuator, such that actuation of the
microactuator moves the transducer relative to the
slider in a direction generally parallel to the
fingers.
The examiner relies on the following references:
