Abstract: In an electroconductive contact unit including an electroconductive coil member received in an axial bore with the axial ends of the coil member projecting from the axial bore so as to serve as contact pin sections, the contact pin sections are formed by closely wound segments of the coil member while the middle part of the coil member is formed as a compression coil spring section for biasing the contact pin sections. The compression coil spring section includes a coarsely wound segment and a normally wound segment. When in use, the adjacent turns of the coil wire of at least the normally wound segment of the coil member are brought into contact with each other so that the coil member is made electrically equivalent to a cylinder in most part, and can thereby minimize its electric inductance and electric resistance.

Abstract: In a magnetic head device, I-shaped side and center cores are fitted to a slider, and magnetic gaps are formed by a part of the slider. Therefore, a magnetic path can be shortened, and the magnetic head device is constructed so as not to leave strains on the cores, so that the core loss is low. In addition, a back core (back plate) having a wide area is provided, so that heat-dissipating effect is enhanced. Therefore, magnetic field-generating efficiency can be improved in wide frequency bands. Further, by decreasing the number of turns of a coil, the inductance, the impedance, and the loss factor can be reduced.

Abstract: A magnetic head for a magneto-optical recording device for magnetically recording information onto a magnetic recording medium under the condition where the magnetic recording medium is heated by irradiation of a laser beam. A leakage magnetic field is effectively suppressed by a skin effect, and a magnetic field due to an eddy current is effectively summed up with a magnetic field generated from the core end, thereby increasing an intensity of a total magnetic field to be applied to the magnetic recording medium. Further, a distribution of the magnetic field intensity at the core end can be easily adjusted to stably and widely apply the magnetic field to the magnetic recording medium.
