AbstractA slider equipped with a magnetic head is pressed on a magnetic disk surface under a constant pressure by a pressing member. The slider is loaded and unloaded by a loading/unloading mechanism. A driving unit of the loading/unloading mechanism has a shape memory alloy member which offers a shape memory effect based on the thermoelastic martensitic transformation, and a resilient member having a resilient force against the driving force of the shape memory alloy member. Moreover, the loading/unloading mechanism is arranged such that when the slide is loaded, the driving force of the loading/unloading mechanism is not applied to the pressing member supporting the slider.
