Abstract
A flexlead circuit assembly is provided for use in a rotary disk storage system and is designed so that the inherent bias force exerted by the flexible circuit on the actuator arm of the disk storage system is negated. The flexlead circuit herein is split into two sets of flexlead conductors: one to supply power and ground to the actuator VCM and other to transmit signals to and from the read/write heads. The end of each of these flexlead conductors opposite to the end mounted to the actuator arm is integrally formed with and provides signal communication with a printed circuit mounted within the housing. The printed circuit is formed on a substrate which is snap-fit to the lower plate of the disk drive housing to thereby not only support the printed circuit within the housing, but also to provide mechanical support for the flexlead circuit.
