Abstract
There is provided a pre-amplifier with a baseplate configured for mounting to an actuator in a disc drive. The baseplate is directly fixed to the actuator at one point, with a damping layer between a second surface of the baseplate and the actuator. The damping layer helps to constrain the baseplate from rotational movement relative to the actuator. Preferably, the baseplate is fixed to the actuator by a grounding pin coupled to the baseplate.
