ABSTRACT:
A head suspension mechanism of a recording apparatus for flexibly carrying a transducer in a floating state. The mechanism comprises a head slider, a load beam, a spring plate, and an adjusting screw. The load beam is composed of a rigid section, a resilient section, and a holding section. The head slider is suspended at the free end of the rigid section through a gimbal. The load beam is secured to a supporting arm of the head actuator of the apparatus at the holding section, and loaded by the spring plate at the resilient section. The load is easily and precisely adjustable using the adjusting screw. Thus, the head slider contacts the disk at rest with a predetermined static load in order to maintain a favorable flying height of the head slider over the rotating disk. With the above configuration, the load provided by the spring plate is substantially increased as compared with the load to be applied to the head slider, enabling the easy and precise adjusting of the loading force.
