Abstract
A data storage disk drive is provided with a spindle which supports a plurality of disks having at least one magnetic disk surface to form a spindle assembly for rotation of the disk surfaces about a common axis and a rotary actuator which supports magnetic transducers for movement in unison about respective disk surfaces. The disk drive includes a voltage reference tab provided for quick assembly and removal from an actuator comb. The voltage reference tab maintains the magneto-resistive transducers and the magnetic disks at the same reference voltage potential thus minimizing electrical discharge from the transducer to the disk. The voltage reference tab is a copper tab having symmetrical slots about a fastening hole to facilitate the bending operation and to reduce the rate at which heat is conducted during the soldering process. The tab maintains the voltage reference potential between the head and disk through an extension of the flex cable attached to the actuator.
