摘要： In a magnetic head supporting apparatus having a second actuator for fine movement in addition to a first actuator having a voice coil motor for coarse movement, the second actuator is fixed so as to bridge the upper surface of a suspension and the upper surface of a suspension supporting member to support the suspension, and the second actuator is a plate-shaped structure which has two polarization regions separated by a non-polarized region and is formed by laminating piezoelectric flat plates in which the polarizing directions and the directions of electric fields to be applied are thickness directions. Thus, a magnetic disk apparatus which can be driven by a low voltage, a displacement in the vertical direction of the suspension is small, a productivity is high, and a recording density is high can be realized.

摘要： The present invention provides a method of making a mold for manufacturing a microlens having a smooth surface and an arbitrary aspherical surface, or more specifically, an aspheric microlens of dimensions such that an aperture is equal to or less than 1 mm and a thickness is equal to or more than 0.5 mm. A mask layer having plural circular apertures with different sizes formed therein for a mold for one lens is formed on a silicon substrate. Plural holes are formed for the lens in the silicon substrate by applying anisotropic dry etching to a surface to be processed, which is the surface having the mask layer formed thereon. The depths of the respective holes vary depending on the sizes of the circular apertures. Isotropic etching is performed to remove sidewalls of the plural holes with different depths formed in the silicon substrate, thereby merging the holes into one hole corresponding to the lens.

摘要： A process for fabricating a mold for an aspherical microlens having a desired aspherical and smooth surface, the lens having an effective diameter of 1 mm or smaller and a thickness of 0.5 mm or greater. A double-layer mask layer is formed on a single crystal silicon substrate, and anisotropic etching and isotropic etching are carried out using a first mask layer so as to form a concave portion that is a little smaller than the size of a desired microlens mold. Isotropic etching is then carried out using a second mask layer so as to enlarge the concave portion, thereby obtaining a microlens mold having desired dimensions.
