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 (M 1 ), 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 (M 1 ) is shaped and transferred onto a flexible recording medium (G 2 ) on which a UV curable resin layer ( 61 ) is formed, whereby an intermediate medium (M 2 ) is prepared (FIGS. (b)-(d)). The inverted recess and protrusion structure transferred to the intermediate medium (M 2 ) is shaped and transferred onto a recording medium (G 3 ) comprising a quartz glass substrate ( 70 ) on which a UV curable resin layer ( 80 ) is formed, whereby a reproduction medium (M 3 ) having the same recess and protrusion structure as that of the master medium (M 1 ) is prepared (FIGS. (e)-(h)). In shaping and transferring process, the media are separated using the flexibility of the intermediate medium (M 2 ).

Claim (Index 8):
The method for manufacturing an information recording medium according to  claim 1 , wherein\n the master medium preparation step includes, a data input step (S 11 ) in which a computer inputs digital data (D) to be stored, a unit data creating step (S 12 ) in which the computer divides the digital data by a prescribed bit length unit to create a plurality of unit data (U 1 ), a unit bit matrix creating step (S 13 ) in which the computer arranges data bits which constitute individual unit data in a two-dimensional matrix form to create a unit bit matrix (B(U 1 )), a unit bit graphic pattern creating step (S 14 ) in which the computer converts the unit bit matrix to a geometrical pattern arranged inside a predetermined bit recording domain, thereby creating a unit bit graphic pattern (P(U 1 )), a unit recording graphic pattern creating step (S 15 ) in which the computer adds an alignment mark to the unit bit graphic pattern, thereby creating a unit recording graphic pattern (R(U 1 )), a drawing data creating step (S 16 ) in which the computer creates drawing data (E) for drawing the unit recording graphic pattern, a beam exposure step (S 17 ) in which beam exposure which uses electron beams or laser light is performed on a substrate in which the resist layer ( 20 ) is added on the first recording medium (G 1 ), thereby conducting drawing on the basis of the drawing data, and a patterning step (S 18 ) in which patterning processing is performed on the substrate which has been exposed, thereby creating the master medium (M 1 ) having a physically structured pattern depending on the drawing data.
