Abstract

Magnetic Spring Return J-Block Flex Cable Bias Tuner in Rotational Actuator with Fewer Suspensions for Load/Unload Technology Disclosed is a system that helps tune fewer armed suspensions in a rotary actuator against flex cable bias within ramp load/unload disk drive designs. Due to the large variation from flex cable to flex cable, it is difficult to maintain actuators with fewer suspensions on the load unload ramp during rotational shocks. The system typically consists of the following parts: 1) Actuator 2) VCM (Voice Coil Motor) and 3) Magnetically Attractive Material Metal Material
