    摘要： There is provided a compact optical disc apparatus having a small footprint actuator. A tracking coil of a swing arm-type actuator is disposed substantially perpendicular to an arm and on the opposite side to an optical disc loading slot with respect to the line connecting the center of rotation of the optical disc to the center of swing movement of the actuator. A pair of permanent magnets are disposed such that they face the tracking coil and they are opposite in polarity. The tracking coil is disposed on both the permanent magnets such that the tracking coil straddles the boundary of the pair of permanent magnets.

    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 head supporting mechanism equipped with a waveguide is provided by which stiffness of the waveguide does not give a large influence to flying-heights and attitudes of a slider. In the head supporting mechanism, the waveguide provided on a suspension is arranged in such a manner that a portion of the waveguide is bent in either an in-plane direction or an out-plane direction of the suspension.

    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.
