Patent ID: 7990657

Claim:
A method for utilizing a plurality of non-magnetic dampers on a voice coil yoke arm to reduce low frequency vibration in a hard disk drive, said method comprising: receiving an actuator comprising: a coil region having a voice coil and a plurality of voice coil yoke arms coupled with said voice coil; and a suspension for reaching over the disk, the suspension having a slider coupled therewith, said slider having a read/write head element on a trailing edge (TE) portion; forming a plurality of non-magnetic dampers from a layer of Aluminum plated on both sides with Nickel without providing an elastic layer between said layer of Aluminum and said two layers of plated Nickel; and coupling at least one of said plurality of non-magnetic dampers with each of said plurality of voice coil yoke arms and not with said voice coil, said plurality of non-magnetic dampers utilized for damping low frequency actuator coil torsion and coil bending resonances.
