  • MEDIUM TRANSPORT DEVICE AND IMAGE READING DEVICE
    Publication number: 20250051118
    Abstract: a medium transport device includes a first roller pair, a second roller pair disposed downstream of the first roller pair, and an ultrasonic detection section disposed between the first roller pair and the second roller pair. The ultrasonic detection section includes a transmission sensor chip, a receiving sensor chip, a transmission board on which the transmission sensor chip is provided, and a receiving board on which the receiving sensor chip is provided. A first axis is inclined with respect to a surface of the medium passing between the transmission sensor chip and the receiving sensor chip and at least a part of the transmission sensor chip and at least a part of the receiving sensor chip are within a range of the second roller pair in a normal direction with respect to a surface of the medium at a nip position of the second roller pair.

  • Magnetic recording medium and manufacturing method thereof
    Publication number: 20060115686
    Abstract: A high-density magnetic recording medium uses a nonmetallic substrate, while still providing high in-plane magnetic anisotropy and remanent coercivity. Such a medium can be formed by depositing a seed layer on a textured surface of the nonmetallic substrate in a gas mixture containing oxygen or nitrogen and an inert gas, while controlling the oxygen concentration or nitrogen concentration, and subsequently exposing the surface of the seed layer to oxygen or nitrogen.
