Abstract
A rotating disk memory apparatus includes an actuator assembly electrical interconnect. Flex circuit tape retainers are provided to substantially reduce and ideally eliminate torque forces on the actuator due to flex circuit bending. The retainers includes a tape guide having an inner wall to conform those portions of the flex circuit proximate both an actuator body member and a base plate connector member to predetermined configurations, such as loops providing a design specific exit angle for the flex circuit at each retainer. The looped portion of the flex circuit is held in the guide by a selectively detachable guide post device. The predetermined configuration is designed to minimize the torque on the actuator from inherent spring forces generated due to bending of the flex circuit during actuator motion relative to the rotating disk.
