  • Patent number: 8295141
    Abstract: The present invention provides a method for forming a pattern, containing: stacking a master having at least a two-dimensional pattern or a three-dimensional pattern formed thereon and a pattern-transferring material containing at least a recording layer which changes a state thereof as light is transmitted thereto; and transmitting light to the recording layer so as to transfer the pattern of the master onto the recording layer.
    Type: Grant
    Filed: December 19, 2008
    Date of Patent: October 23, 2012
    Assignee: Ricoh Company, Ltd.
    Inventors: Hiroshi Deguchi, Kawori Tanaka
  • Patent number: 8147942
    Abstract: A write-once-read-many optical recording medium is disclosed that includes a support substrate; a recording layer on the support substrate, the recording layer containing an oxide of one of a metal and a metalloid as a principal component; and a layer adjacent to the recording layer. The recording layer includes a region where a constituent element of the adjacent layer is dispersed. Recording and reproduction are performable with laser light of a blue wavelength region.

  • Publication number: 20090230594
    Abstract: An imprint method of, in a state in which an indented surface of a mold comes in contact with a to-be-transferred surface of a to-be-transferred object, irradiating with electromagnetic waves to soften the to-be-transferred surface, and transferring an indented shape of the indented surface to the to-be-transferred surface, includes a heating layer forming step of forming, on the indented surface, a heating layer which absorbs the electromagnetic waves and generates heat; and a softening step of irradiating the heating layer with the electromagnetic waves, through the mold or the to-be-transferred object, at least one of the mold and the to-be-transferred object being made of a material which transmits the electromagnetic waves, causing the heating layer to generate heat, and softening the to-be-transferred surface.

  • Patent number: 7413788
    Abstract: For recording information at high density even at blue-laser wavelengths, a write-once-read-many optical recording medium includes a first inorganic thin film and at least one of a second inorganic thin film and an organic thin film, in which the first inorganic thin film contains at least “R” and “O,” wherein “R” is at least one selected from Y, Bi, In, Mo, V and lanthanum series elements; and “O” is oxygen atom, and the second inorganic thin film and the organic thin film are capable of suppressing at least one of deformation and breakage of the first inorganic thin film and receiving the change of state of the first inorganic thin film.
