A spindle system is comprised or a journal and thrust air bearing. The journal bearing; has two sets of opposing groove areas. The thrust air bearing has two sets of spiral grooves. The thrust air bearing is gimballed to compensate for misaligment. A bias contact member is connected to the rotating member along the axis of rotation and provides electrical grounding, The spindle system is especially applicable to mounting recording disks in a data storage disk drive.

A thin film magnetic read/write head/arm assembly and method of manufacturing the same is disclosed herein. Contact soldering of the opposite to disk side of the read/write head to a cable in laminate relationship to the suspension arm, or a polyimide strip with conductors deposited thereon provides both electrical interconnection and mechanical support. Semiconductor devices can also be intermediately soldered between the head and cable for maximum noise suppression.
