  • Patent number: 6999287
    Abstract: A magneto-resistance effect head is provided with a lower conductive layer which is provided with a recessed portion, and a vertical bias layer is provided in the recessed portion. A free layer is provided on the lower conductive layer. On the free layer, layered in the following order are the non-magnetic layer, the fixed layer, the fixing layer, and the upper layer so as not to be placed immediately above the vertical bias layer. The non-magnetic layer, the fixed layer, the fixing layer, and the upper layer are buried in an insulation layer. Furthermore, an upper conductive layer is provided on the upper layer and the insulation layer. In the direction of the magnetic field applied by the vertical bias layer, the free layer is made greater in length than the fixed layer and the free layer is disposed in proximity to the vertical bias layer with the distance between the fixed layer and the vertical bias layer remaining unchanged.

  • Publication number: 20050044895
    Abstract: The invention relates to a method for putting color to glass by irradiating a silicate glass, containing a non-bridging oxygen in its structure, with a laser light, thereby forming a non-bridging oxygen hole center therein to put a color to the glass. The invention further relates to a method for putting color to glass by irradiating a silver-ion-containing glass with a high-energy light, thereby forming silver particles in the glass through aggregation of silver ions to put a color to the glass. The invention further relates to a method for erasing color from colored glass by irradiating a colored portion of a glass with a laser light to selectively heat the colored portion by using a laser irradiation apparatus comprising (a) a laser oscillator, (b) a light modulator, (c) a condenser lens mounted on a linear translator, (d) an objective lens, and (e) a galvanometer mirror.

  • Publication number: 20050019610
    Abstract: In a spin tunnel magnetoresistive effect film in which a magnetic thin film to which an exchange bias is applied by exchange coupling via an anti-ferromagnetic thin film and a magnetic thin film that detects a magnetic field are laminated, a magnetic thin film or an anti-ferromagnetic thin film (PtMn, PdMn, NiMn) is laminated onto an underlayer (Ta, Zr, Hf), the surface roughness thereof being in the range from 0.1 to 5 Angstroms. A means used to control the surface roughness introduces into the film growing chamber oxygen, nitrogen, hydrogen, or a gas mixture thereof into a vacuum of 10?6 Torr to 10?9 Torr, reduces the substrate temperature to 0° C. or lower during film growth, or oxidizes an underlayer. The lower electrode layer material used is a film laminate of a high-permeability amorphous magnetic material and a non-magnetic metallic layer.
