Abstract
A method and apparatus for electrically coupling a slider to a controller circuit are disclosed. In one embodiment, a pre-amplifier with an integrated electrical connector (I-connector) may be connected via an electrical trace to a slider and via a head stack assembly flexible circuit to a control circuit. The pre-amplifier may have two parallel series of spring probe claws, two parallel series of contact pegs, two slots, or a slot and a rotary cam.
