Beschreibung
Zusammenfassung:	A damper for dampening resonance created by a voice coil motor of a disc drive and transmitted to a supporting enclosure, the resonance capable of creating noise signals to the disc drive servo control system. The damper has a dampening member and a liner, the liner being a magnetically permeable member that is magnetically attracted to the voice coil motor and thereby pressingly engaging a magnet housing of the voice coil motor. In a preferred embodiment the dampening member is an acrylic polymer. In an alternative embodiment the dampening member is a fluoroelastomer. The magnet housing has characteristic features that increase the magnetic flux to the liner.
