Abstract

The present invention is aimed to provide a head suspension having a high resonant frequency, high shock resistance and low rigidity, which greatly contributes to an improvement of a magnetic disk apparatus. In an oscillation-type actuator, at least a part of a spring arm of the head suspension having a data reading/writing head slider 1 is made of an anisotropic layer whose rigidity varies in accordance with a direction. In this case, the anisotropic layer is laminated so that the high rigidity modulus orientation direction is different according to layer.
