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 61):
An information readout method by which digital data stored in an information recording medium by using an information storage method, is read out,\n said information storage method, comprising: a data input step in which a computer inputs digital data to be stored; a unit data creating step in which the computer divides the digital data into a prescribed bit length unit to create a plurality of unit data; a unit bit matrix creating step in which the computer arranges data bits which constitute individual unit data in a two-dimensional matrix form to create a unit bit matrix; a unit bit graphic pattern creating step 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; a unit recording graphic pattern creating step in which the computer adds an alignment mark to the unit bit graphic pattern, thereby creating a unit recording graphic pattern; a drawing data creating step in which the computer creates drawing data for drawing the unit recording graphic pattern; a beam exposure step in which beam exposure is performed by using electron beams or laser light on a substrate which acts as the information recording medium on the basis of the drawing data; and a patterning step in which pattern processing is performed on the substrate which has been exposed, thereby creating the information recording medium in which a physically structured pattern is formed according to the drawing data; and said information readout method, comprising: an image photographing step in which a domain to be photographed which is a part of a recording surface of the information recording medium is magnified and photographed by using an image photographing device and an obtained photographed image is captured as image data; a photographed-image housing step in which a computer houses the photographed image; a bit-recording-domain recognizing step in which the computer detects an alignment mark from the photographed image housed by the photographed image housing step, thereby recognizing individual bit recording domains; a unit-bit-matrix recognizing step in which the computer recognizes a unit bit matrix on the basis of a pattern inside the bit recording domain; and a data restoration step in which the computer creates unit data from individual unit bit matrixes recognized in the unit-bit-matrix recognizing step to synthesize individual unit data, thereby restoring digital data stored, wherein in the image photographing step, the computer controls a change of a domain to be photographed by the image photographing device so that a photographed image can be obtained in all bit recording domains to be read out.
