A disk drive data storage system. The system comprises a data storage disk, a movable member positioned near the data storage disk, and a sensor assembly, supported and movable by the movable member, for writing data to and reading data from the data storage disk. The system also comprises an integrated circuit that is electrically coupled to the sensor assembly and that moves with the movable member when the movable member moves the sensor assembly. The integrated circuit comprises a face and a backside, and the integrated circuit is in a fixed physical position relative to the movable member such that the backside is oriented toward the movable member.
