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 56):
An information readout device which reads out digital data stored at an information recording medium by using the information storage device according to  claim 43 ,\n the information readout device, comprising: an image photographing device which magnifies and photographs a domain to be photographed which is a part of a recording surface of the information recording medium to capture an obtained photographed image as image data; a photographed-image housing portion which houses the photographed image; a bit-recording-domain recognizing portion which detects an alignment mark from the photographed image housed in the photographed-image housing portion, thereby recognizing individual bit recording domains; a unit-bit-matrix recognizing portion which recognizes a unit bit matrix on the basis of a pattern inside the bit recording domain; a scanning controller which controls a change in domain to be photographed by the image photographing device so that a photographed image can be obtained in all bit recording domains to be readout; and a data restoration portion which creates unit data from individual unit bit matrixes recognized by the unit-bit-matrix recognizing portion to synthesize individual unit data, thereby restoring the digital data stored.
