Appeal No. 2000-1890
Application 08/828,297
More particularly, the drive suspension has a load beam with one
or more mass balancing structures placed thereon in a first
configuration. The mass balancing structures are adjusted to a
second configuration responsive to a measurement representative
of a resonance characteristic of the suspension.
Representative claims 1 and 16 are reproduced as follows:
1. A disk drive suspension adjusted for enhanced
resonance performance including a load beam having a distal end,
an actuator arm mounting region on a proximal end, a rigid
region, a spring region between the rigid region and actuator arm
mounting region, and a head mounting region on a distal end of
the load beam for receiving a transducer head, the load beam
having one or more mass balancing structures in a first
configuration between the actuator arm mounting region and the
head mounting region, the disk drive suspension comprising:
the one or more mass balancing structures being adjusted
to a second configuration in response to a measurement
representative of a resonance characteristic of the suspension to
controllably adjust the mass distribution of the load beam and
the resonance characteristic to a desired value.
16. A method for adjusting one or more resonance
characteristics of disk drive suspensions of the type including a
load beam having proximal and distal ends, an actuator arm
mounting region on the proximal end and a transducer mounting
region on a distal end, the method including:
forming a disk drive suspension with one or more mass
balancing structures positioned in a first configuration at
adjust locations on the load beam, the adjust locations being
where a resonance characteristic to be adjusted is sensitive to
changes in mass;
measuring the resonance characteristic of the suspension;
and
