A design of high performance inline head assembly for high-speed access

A high-performance inline head assembly that stabilizes head sliders during high-speed access has been developed. It features a triangular, truss-bridge-shaped load beam and a flexure supported at both ends by the load beam. These improvements made the resonant frequency in the access direction twice that of the conventional inline head assembly, reducing spacing fluctuation at high frequencies and allowing the actuator to be positioned more precisely. The proturberance was moved to the load beam from the flexure, lowering the moment by decreasing the distance between where the force was applied to the slider and the slider´s center of gravity. Experiments showed that the resonant frequency of the inline head assembly is 8 kHz in the access direction, which is about twice that of the conventional inline head assembly. Spacing fluctuation is about 50% that of the conventional inline head assembly
