Appeal No. 1999-2285
Application 08/826,277
magnetic head suspensions for supporting a magnetic head at a
fixed distance from a rigid arm. More particularly, the
invention relates to a unitary flexure and load beam formed
from a single sheet of material.
Representative claim 25 is reproduced as follows:
25. In a magnetic head suspension for supporting a
magnetic head at a fixed distance from a rigid arm, a unitary
flexure and load beam formed from a single sheet of material,
said suspension comprising:
a. a spring load beam element portion joined to the
arm at a proximal end thereof; and
b. a flexure portion projecting beyond a distal apex
of the spring load beam element portion, the flexure portion
being divided into a central head mounting support means
having an arcuate perimeter for receiving a disk drive head to
be bonded thereto;
a first plurality of arcuate slots in a surface of the
flexure portion around substantially an entire perimeter of
the support means with exception of two gimbal support pivots
aligned on opposite sides of the support means to define a
first set of arcuate flexible arms for gimbal supporting the
support means about a first rotational axis of the support
means; and
a second plurality of arcuate slots in the surface of
the flexure portion around substantially the entire perimeter
of the support means and around the first plurality of arcuate
slots with exception of two gimbal support pivots aligned on
opposite sides of the support means to define a second set of
arcuate flexible arms for gimbal supporting the support means
about a second rotational axis of the support means which is
angularly offset from the first rotational axis;
