Abstract:
The invention makes it possible to perform highly integrated recording of information and read out the information in a universal method while maintaining long-term durability. Digital data (D) to be stored is divided by a prescribed bit length u to create a plurality of unit data (U 1  to U 4 ). The bits constituting the unit data (U 1 ) are arranged in a two-dimensional matrix to create a unit bit matrix (B(U 1 )), which is converted to a geometrical pattern to thereby create a unit bit graphic pattern (P(U 1 )). Further, alignment marks (Q) are arranged at four corners to create a unit recording graphic pattern (R(U 1 )). A drawing pattern (P(E)) is created as an assembly of the unit recording graphic patterns (R(U 1 ) to R(U 4 )), and is provided to an electron beam lithography system as drawing data (E) whereby a pattern is drawn in a resist layer on a glass substrate. The resist layer is developed and the glass substrate is etched, and thus the digital data (D) is recorded on the substrate as a physically structured pattern.

Claim (Index 46):
The information storage device according to  claim 45 , wherein\n the patterning device forms a physically structured pattern having an added layer made of a light reflective material or a light absorbing material on a surface of one of a recess and a protrusion or on surfaces of both of them.
