  • Magnetic recording medium and method of producing the same
    Publication number: 20030059648
    Abstract: A magnetic recording medium for high areal recording density that has excellent thermal fluctuation resistance and recording/reproduction characteristics, and a method of producing the same. The magnetic recording medium includes a glass substrate, an NiP layer having an oxide film on its surface provided on the glass substrate, a ground layer provided on the NiP layer, and a nonmagnetic intermediate layer provided on the ground layer. The magnetic recording medium further includes an exchange layer structure composed of a ferromagnetic layer and a nonmagnetic coupling layer provided on the nonmagnetic intermediate layer, and a magnetic recording layer provided on the exchange layer structure. The oxide film on the NiP layer is formed by introducing a small quantity of oxygen into a vacuum chamber of a sputter device. The formation and oxidation of the NiP layer are conducted at a temperature of not less than 140° C.

  • Pellet handling and external inspection equipment
    Patent number: 5019326
    Abstract: The present invention provides a pellet handling equipment for conveying pellets. The pellet handling equipment is essentially composed of a first roller device, a second roller device, and a pellet supplying device. The first roller device is supported generally horizontal and rotatable about an axis thereof for a rotation in a predetermined direction. The second roller device is disposed parallel and adjacent to the first roller device, supported rotatable about an axis thereof for a rotation in a same direction with the first roller device. The second roller device is provided with a slot formed in a circumferential surface thereof and extending in the axial direction. The slot is capable of receiving each one of the pellets. The pellet supplying device intermittently supplies the pellets to the first and second roller device.
