Title: Magnetic recording method and magnetic recording medium
Inventor: TAKAHASHI TERUO
IPC: G11B5/02
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To discriminate and read out adjacent memory pits by bringing a head into contact with the recording bits of a magnetic recording medium consisting of a reproducing layer of which the axis of easy magnetization exists in the plane direction of a disk or tape and a recording layer of which the axis of easy magnetization exists in a plane normal direction and changing the magnetic anisotropy of this part of the reproducing layer. SOLUTION: The reproducing layer 1 is so formed of, for example, GdFeCo, CoCr based alloys, etc., of a large magnetostriction constant in such a manner that the magnetic anisotropy faces the inside of the plane. The recording layer 3 is so formed of TbFeCo, CoCr based alloys having large coercive force in such a manner that the magnetic anisotropy faces the plane normal. The magnetic anisotropy of the reproducing layer faces the plane normal direction in such a manner as to be weakened and is dragged by the magnetization of the recording layer when a pressure is applied or temp. is raised at the time of reproduction.  The magnetization 2 of the reproduction layer under the pressure of the probe-like magnetic head 6 is weakened in the magnetic anisotropy by magnetostriction and is changed to the direction of the magnetization 4 of the recording layer and, therefore the direction of a magnetic flux 5 may be discriminated from the magnetic flux from the adjacent recording bits.

Abstract: PURPOSE:To lessen a voltage drop in a power supply wiring by a method wherein the wiring of a custom integrated circuit is formed into such a constitution that a power supply wiring width and a reference voltage wiring width are made as narrow as possible before an intermacrocell wiring is provided to secure a sufficient channel region and the intermacrocell wiring can be provided to any requirement from users. CONSTITUTION:A power supply wiring 501 set previously in a second wiring layer is expanded into two-layer channel regions and the wiring 501 is used as an expanded power supply wiring 504. After an intermacrocell wiring program process ends, a power supply wiring width is expanded at a region, on where an intermacrocell wiring is not laid, of two-layer channel regions 701 and 702 and a power supply wiring 501 is reset as an expanded power supply wiring 504. In respect to a reference voltage wiring 601 as well the same wiring width is expanded, whereby the wiring 601 is reset as an expanded reference voltage wiring 602. The wiring resistance of the power supply wiring is decreased. Thereby, a voltage drop in the power supply wiring is reduced and an erroneous decision on a logical level is decreased. Moreover, by an increase in the wiring capacitance of the wiring resistance of the power supply wiring, the rate of absorption of generated noise is increased and by an increase in the wiring capacitance of the reference voltage wiring, the rate of absorption of noise transmitted here is increased.
