    摘要: A slider including a magnetic head part, an optical waveguide, and a near field element is fixed by first and second adhesives to a submount on which a semiconductor laser and a mirror are mounted, the mirror being placed at one end of the semiconductor laser in a resonance direction thereof and reflecting a laser in a direction intersecting with the resonance direction. At this time, at least parts of the first and second adhesives are applied to a position opposed to the semiconductor laser with an intermediation of the submount. The first adhesive having a higher Young's modulus than that of the second adhesive is applied onto an inflow end side of the slider including a solder connection portion, the second adhesive being applied onto an outflow end side of the slider.

    摘要: In laser welding an optical part to a pickup case of an optical pickup device, outgas deposition on a lens surface can be inhibited, and positional shifting of the optical part can be reduced. The optical part has a lens surface facing in an optical axis direction and a protruding part formed, to be joined to the pickup case, at an end portion thereof in a direction perpendicular to the optical axis. A joint surface between the protruding part and the pickup case extends in a direction parallel to the optical axis, and the joint surface is fixed by a weld portion formed by laser irradiation. The joint surface is parallel to a bottom surface of the pickup case, and the height from the bottom surface is approximately equal to the height of the center of the lens surface.

    摘要: A multilayer printed circuit board includes an inner magnetic layer essentially consisting of magnetic material. The inner magnetic layer may be formed by an action of chemical bond or van der Waals force. The inner magnetic layer may comprise a plurality of magnetic units, each of which provides magnetism, and may be formed by magnetically coupling the magnetic units with each other by using a strong interaction. The inner magnetic layer may essentially consist of a ferrite film. The ferrite film may be formed directly on the inner conductive layer by means of an electroless plating method. The ferrite film may essentially consist of an oxide metal composition, the metal composition being represented by the formula of FeaNibZncCod, where: a+b+c+d=3.0; 2.1≦a≦2.7; 0.1≦b≦0.3; 0.1≦c≦0.7; and 0≦d≦0.15.

    摘要: A heating device capable of evenly heating a thermal recording medium without increasing the cost of the device is disclosed. The heating device evenly heats the recording surface of a thermally-reversible recording card by conducting the heat energy transferred from a heat generating member by way of a heating member, made of aluminum having high heat conductivity and high heat capacity characteristics. By this feature, it becomes possible to accurately erase the information recorded on the recording card and to use an inexpensive heat generating member as the heat generating member.
