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 1):
A method for manufacturing an information recording medium which prepares a plurality of information recording media in which a same digital data has been recorded, the method comprising:\n a master medium preparation step in which a process for recording digital data to be stored as a recess and protrusion structure pattern on a recording surface of a first recording medium (G 1 ) is performed to prepare a master medium (M 1 ); an intermediate medium preparation step in which a process for transferring the recess and protrusion structure pattern recorded at the master medium (M  1 ) onto a recording surface of a second recording medium (G 2 ) is performed to prepare an intermediate medium (M 2 ); and a reproduction medium preparation step in which a process for transferring the recess and protrusion structure pattern recorded at the intermediate medium (M 2 ) on a recording surface of a third recording medium (G 3 ) is performed to prepare a reproduction medium (M 3 ); wherein in the master medium preparation step, a medium which includes a quartz glass substrate ( 10 ) as the first recording medium (G 1 ) is used to form a resist layer ( 20 ) on a surface of the first recording medium (G 1 ), beam exposure is performed on a surface of the resist layer to draw a graphic pattern which shows bit information of digital data to be stored, the resist layer is developed to remove a part thereof, etching processing is performed, with a remaining part ( 23 ) of the resist layer given as a mask, thereby preparing the master medium (M 1 ) which includes a quartz glass substrate ( 11 ) having a first recess and protrusion structure pattern on a surface thereof, in the intermediate medium preparation step, a shape formation process which utilizes the first recess and protrusion structure pattern formed on the surface of the master medium (M 1 ) is performed to form, on the recording surface of the second recording medium (G 2 ), a second recess and protrusion structure pattern which is reverse in recess and protrusion relationship to the first recess and protrusion structure pattern, in the reproduction medium preparation step, a medium which includes a quartz glass substrate ( 70 ) as the third recording medium (G 3 ) is used to form, on the recording surface of the third recording medium (G 3 ), a third recess and protrusion structure pattern which is reverse in recess and protrusion relationship to the second recess and protrusion structure pattern by a shape formation process which utilizes the second recess and protrusion structure pattern formed on the surface of the intermediate medium (M 2 ), and when the first recording medium (G 1 ) and the third recording medium (G 3 ) are referred to as a first attribute medium and the second recording medium (G 2 ) is referred to as a second attribute medium, at least one of the first attribute medium and the second attribute medium has flexibility, and in the shape formation process of the intermediate medium preparation step and the shape formation process of the reproduction medium preparation step, a medium having flexibility is curved and peeled from another medium.
