    摘要： In the method for making the magnetic recording wherein a first magnetic layer is formed on a substrate and a second magnetic layer is formed on the first magnetic layer, before forming the second magnetic layer, accelerated ions are irradiated onto a surface of the first magnetic layer. Thereby, naturally formed oxidized layer and adhered impurity on the first magnetic layer are removed from the surface of the first magnetic layer by ion etching action by the irradiation of ions, and hence a preferable condition of an interface between the first magnetic layer and subsequently formed second magnetic layer is obtained.

    摘要： The method includes applying ions and electrons from an ion gun onto a polymer film while the polymer film is traveling circumferentially along a peripheral surface of a cylindrical can from a supply location to a take-up location of the polymer film relative to the cylindrical drum. The ions and electrons from the ion gun are applied onto a part of the polymer film while it is moving through a position near the supply location of the polymer film relative to the drum at which the polymer film begins to contact the outer peripheral surface of the drum. At a downstream location relative to the drum, electrons are applied from an electron gun onto the polymer film traveling on the drum surface. At a further downstream location relative to the drum, the thin film is deposited, e.g., by vacuum evaporation, on the polymer film travelling on the drum. This method enables a thin film, having no wrinkles and with a high adhesion strength with respect to the polymer film, to be produced in a stable manner.

    摘要： The magnetoresistive device of the present invention includes: at least two magnetic layers stacked via a non-magnetic layer therebetween; and a metal reflective layer of conduction electrons formed so as to be in contact with at least one of outermost two layers of the magnetic layers. The metal reflective layer is in contact with one surface of the outermost magnetic layer which is opposite to the other surface of the outermost magnetic layer in contact with the non-magnetic layer. The metal reflective layer is likely to reflect conduction electrons while maintaining a spin direction of electrons.
