    摘要： A head support mechanism includes a slider equipped with a magnetic head to read/write information from/to a magnetic disk, a load beam to provide the slider with an appropriate load, the load beam being flexible in a direction substantially perpendicular to the disk, and a microactuator mounting portion equipped with a microactuator. A first actuator fixing portion, which connects the microactuator mounting portion to a carriage, and a second actuator fixing portion on the magnetic head side of the microactuator mounting portion, which connects the microactuator mounting portion to the load beam, are coupled by two arm portions of the microactuator mounting portion. The microactuator is mounted on the microactuator mounting portion so that the microactuator does not come into contact with the microactuator mounting portion between the first actuator fixing portion and the second actuator fixing portion.

    摘要： A magnetic disk apparatus of the present invention is equipped with a microactuator for micro motion using piezoelectric elements in addition to a coarse adjustment actuator such as a voice coil motor or the like, eliminates parts that slide between the microactuator and surrounding members, and alleviates stress on the piezoelectric elements even if an impact is given to the magnetic disk apparatus. Thus, a first actuator fixing portion on a carriage side and a second actuator fixing portion on a magnetic head side of a microactuator mounting portion are coupled with a plurality of flexible coupling portions and coupling portions are placed outside the microactuator in substantially symmetric with respect to a centerline in a longitudinal direction of a suspension.

    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.
