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： There is provided a thermally assisted magnetic recording device capable of preventing collision between a thermally assisted magnetic recording head and a disk due to thermal deformation of a near-field transducer. The thermally assisted magnetic recording device includes a temperature sensor for measuring the temperature in the vicinity of the near-field transducer, a table that stores the relationship between temperature and deformation in the vicinity of the near-field transducer, and a control unit. The control unit calculates the deformation in the vicinity of the near-field transducer, from the temperature measured by the temperature sensor and the relationship between temperature and deformation stored in the table. Then, the control unit drives the flying height control actuator according to the calculated deformation to control the distance between the thermally assisted magnetic recording and the disk in order to avoid contact between them.

摘要： A thermally assisted magnetic recording head with highly efficient optical coupling, while guiding a laser beam from a semiconductor laser element, i.e., a light source, to a leading end thereof, eliminating an influence due to heat generated by the element, and having excellent floating characteristics. The thermally assisted magnetic recording head includes a substrate 2 having a first optical waveguide 1, a semiconductor laser element 100, and a slider 4 having a second optical waveguide 3 formed on an end surface. The semiconductor laser element 100 is fixed on the substrate 2 so that light emitted from the element 100 propagates through the first optical waveguide 1 and a slider 4 is fixed on the substrate 2 so that light emitted from the first optical waveguide 1 propagates through the second optical waveguide 3. High optical coupling efficiency is then achieved, while ensuring both heat-dissipating and floating characteristics.

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.
