Abstract: Provided are: an imprinting method which suppresses volatilization of a photocurable resin applied on a transfer-receiving substrate by an inkjet method, satisfactorily maintains the wet-spreading property of the resin at the time of transfer, maintains cleanness of the environment for transfer, and can fill the environment for transfer with a particular gas appropriate for transfer; and an imprinting apparatus. Disclosed is an imprinting method of using a template having a concavo-convex pattern formed thereon, and transferring the pattern of the template by imprinting to a photocurable resin on a transfer-receiving substrate, characterized in that, in a space where the template and the photocurable resin are brought into contact, clean air is sent to the space through an air blowing port during a standby mode of not performing imprinting, and the flow rate of clean air in the space is reduced or clean air is not sent during an imprinting mode.

Abstract: The same digital data is recorded with highly integrated manner on a plurality of media able to durably hold information over long-term. A minute graphic pattern indicating data bit information is drawn on a resist layer formed on a quartz glass substrate by exposing a beam and developed so as to prepare a master medium (M1), which comprises the quartz glass substrate having a minute recess and protrusion structure formed by etching where the remaining resist are used as a mask (FIG. (a)). The recess and protrusion structure recorded on the master medium (M1) is shaped and transferred onto a flexible recording medium (G2) on which a UV curable resin layer (61) is formed, whereby an intermediate medium (M2) is prepared (FIGS. (b)-(d)).

Abstract: A data storage medium includes a convexoconcave structure formed in a storage area which is set on a first surface of a quartz glass substrate. The storage area includes a plurality of unit storage areas which are arrayed at least in one direction, and non-data storage areas which are disposed between the unit storage areas, which are adjacent to each other. The convexoconcave structure includes unit data patterns, address patterns and boundary patterns. The unit data patterns are formed in the plurality of unit storage areas respectively in the array sequence of the unit storage areas, and the address patterns are formed in the non-data storage areas so as to correspond to each of the unit storage areas in which the unit data patterns are formed respectively.

Abstract: A fine spherical particle formed of diamond as a core and having carbon nano-materials radially grown therefrom is disclosed, which exhibits the appearance of a Marimo (Cladophora sauteri) particle. Fine diamond catalytic particles 2 whose surfaces are oxidized and treated to carry a transition metal catalyst are floated and stirred in a gas phase of hydrocarbon while being heated at a selected temperature to bring about a catalytic reaction which synthesizes carbon nano-materials and to grow them on the surface of said oxidized fine diamond particle. Nano fibers or filaments 32 of a nano size are grown from the fine diamond catalytic particle 31 as a core to form cladophora-form carbon. The carbon nano-materials if the supported transition metal is Ni or Co become carbon nano-tubes and if it is Pd become coin stacked carbon nano-graphite.
