    摘要： A semiconductor device having good electrical properties, and a method of manufacturing this semiconductor device by forming an insulation layer on a first wiring layer and then, in this insulation layer, simultaneously forming a second wiring layer and a contact layer for connecting the first wiring layer and the second wiring layer. A first mask having an opening over a wiring trench in which the second wiring layer will be formed is formed on the insulation layer. A second mask having an opening for a through-hole where the contact layer is to be formed is then formed over the insulation layer and first mask. The insulation layer is then etched using the second mask as a mask. Then the insulation layer is again etched using the first mask as a mask to form wiring trench and through-hole. The wiring trench and through-hole are then filled with a conductive material to form the second wiring layer and contact layer.

    摘要： Disclosed is a magnetic head apparatus, which comprises a pair of magnetic cores defining a magnetic gap for recording and reproducing information, and grooves in the lateral faces of the magnetic cores, extending at right angles to those faces of the cores which are opposed to a magnetic recording medium or which define the magnetic cores. The grooves determine the width of the magnetic gap. That face of at least one of the magnetic cores which is opposed to the recording medium, is recessed from the remaining portion of the core, so as to cover a width equivalent to the length of the grooves, at the maximum. In the magnetic head of the invention, moreover, a nonmagnetic portion is formed at least on an erase gap, so that the degree of magnetic coupling between the erase gap and the recording medium is lower than that between a read/write gap and the medium. Thus, magnetic induction, which is produced in the erase core when data is read from the medium, is reduced.

    摘要： A magnetic disc apparatus obtained by housing in a cartridge case, a magnetic disc which is obtained by forming a metallic magnetic sheet on a polymer base and liner sheets. The liner sheet which is installed between the magnetic disc and the cartridge case has an outer diameter which is smaller than the diameter of the magnetic disc, and an inner diameter which is greater than the rotational diameter of an index hole that is prepared on the magnetic disc for detecting the rotational position of the disc. By arranging in this manner, a smooth rotation of the magnetic disc can be accomplished by avoiding the contact with liner sheet of the edges on the outer periphery of the disc that were bent at the time the disc was punched from the magnetic recording medium, and of the edges of the index hole that were bent at the time the index hole was punched.

    摘要： A bias circuit includes one or more first Zener diodes electrically coupled to a member provided in a replacement unit, the one or more first Zener diodes being coupled in series. When the replacement unit is removably attached to a main unit including a power supply that has one or more second Zener diodes coupled in series, the first Zener diodes are electrically coupled to the second Zener diodes in parallel to change a bias voltage to be applied to the member, the bias voltage being supplied by the power supply. A total absolute value of breakdown voltages across the first Zener diodes is lower than a total absolute value of breakdown voltages across the second Zener diodes.
