摘要： A microlens array sheet includes a light-shielding base having a first surface and a second surface opposite to the first surface and a microlens array attached to the first surface of the light-shielding base, the array having a plurality of microlens. The light-shielding base has a plurality of apertures that correspond to the microlenses. Each aperture has a conical trapezoid-like shape in which a size of each aperture on the first surface side is larger than another size of each aperture on the second surface side. Instead of the light-shielding base, the microlens array sheet may include a transparent base having a first surface and a second surface opposite to the first surface and a light-shielding layer, having a third surface and a fourth surface opposite to the third surface, provided on the second surface of the transparent base. The microlens array is attached to the first surface of the transparent base. The light-shielding layer has a plurality of apertures that correspond to the microlenses. Each aperture has a conical trapezoid-like shape in which a size of each aperture on the third surface side is larger than another size of each aperture on the fourth surface side.

摘要： A thin film magnetic recording medium (30) is composed of an underlayer film (32), which is constituted by a nonmagnetic metal oxide film and formed on a nonmagnetic substrate (31), and a magnetic film (33) of Co system, which is formed on the underlayer film (32) through an oblique evaporation process, wherein each of the underlayer film and the magnetic film is laminated in order. Fine particles of the nonmagnetic metal oxide film grow isotropically in the underlayer film (32) constituted by the nonmagnetic metal oxide film and the underlayer film (32) is formed in a construction without having a clear grain boundary, which separates a aggregation of the fine particles.

摘要： In a first forming process, by injecting a predetermined amount of oxygen gas, magnetic metal vapor 7a is deposited as a nonmagnetic underlayer on a base film F wound on one film winding roll 3B while advancing the base film F in a reverse direction (second direction) toward another film winding roll 3A along a cooling can roll 5 from a minimum incidence angle side to a maximum incidence angle side of an incidence angle controlling mask 9. In a second forming process, by injecting a extremely smaller amount of oxygen gas than in the first forming process, magnetic metal vapor 7a is deposited as a magnetic layer over the nonmagnetic underlayer while advancing the base film deposited with the nonmagnetic underlayer wound on the other film winding roll 3A in a forward direction (first direction) toward the film winding roll 3B along the cooling can roll 5 from the maximum incidence angle side to the minimum incidence angle side of the incidence angle controlling mask 9.
