Systems and methods for information storage
A product with stored non-sequential data may be provided using a method that codes the data to a coding pattern using at least one sequence with symbols. The coding pattern may be configured such that an arbitrary subsequence of a predetermined magnitude of the sequence unambiguously defines the position of the subsequence in the sequence. The coding pattern may be reproduced on a product. An apparatus may be adapted to record and decode the coding pattern.

18 . A system for storing non-sequential data, comprising:
a product; and
a coding pattern placed on an area of the product and coding non-sequential data, the coding pattern including sequence portions with symbols, each sequence portion including at least a subsequence of a sequence which is arranged so that an arbitrary subsequence of a predetermined magnitude of the sequence unambiguously defines a position of the subsequence in the sequence the coding pattern further coding a position sequence representing position within the area of the product.
19 . The system of claim 18 , wherein the coding pattern codes a set of data values, each of the data values coding a group of sequence portions consisting of at least two sequence portions.
20 . The system of claim 18 , wherein the symbols consist of markings, the size of the markings defining a value of the symbol.
21 . The system of claim 18 , wherein each of the symbols comprises a raster point and a marking, the value of each symbol being indicated by a position of said marking in relation to the raster point.
22 . The system of claim 18 , wherein the product comprises at least one of the following: a sheet of paper, a book cover, a page of a book, a magazine cover, a magazine page, a newspaper page, and a bulletin board.
23 . The system of claim 18 , wherein the coding pattern codes text.
24 . The system of claim 18 , wherein the coding pattern codes a command.

31 . A coding pattern data structure for storage of non-sequential data, comprising:
a coding pattern including,
a plurality of symbols provided on a surface and forming a plurality of sequence portions on the surface;
each sequence portion comprising at least a subsequence of a symbol sequence arranged so that an arbitrary subsequence of a predetermined magnitude of the symbol sequence unambiguously defines the position of the subsequence in the symbol sequence.
32 . The coding pattern data structure of claim 31 , wherein each of the symbols includes a raster point and a marking, a value of each symbol being indicated by a position of said marking in relation to the raster point.

40 . A method for storage of data, comprising:
coding the data to a coding pattern, the coding pattern including at least one sequence with symbols which have the characteristic that an arbitrary subsequence of a predetermined magnitude of the sequence unambiguously defines a position of the subsequence in the sequence; and
reproducing the coding pattern on a product with symbols readable with an symbol sensing wand.
41 . The method of claim 40 wherein said step of reproducing the coding pattern imprints or otherwise affixes symbols on said product over a desired symbol bearing area, the coding pattern having coded therein a position sequence representing position within the area of the product.
42 . The method of claim 41 wherein said coding pattern codes a position sequence representing position in said desired symbol bearing area in at least one dimension.
43 . The system of claim 18 wherein said coding pattern covers the entirety of the area of the product.
44 . The system of claim 18 wherein said coding pattern codes a position sequence representing position in said area in one dimension.
45 . The system of claim 44 wherein said coding pattern covers the entirety of the area of the product.
46 . The data structure of claim 31 wherein said non-sequential data is text data.
47 . The coding pattern of claim 31 wherein said coding pattern is affixed to the surface and readable by a digital sensor.
48 . The data structure of claim 31 wherein the data structure is imprinted on a desired area of the surface, the coding pattern further coding a position sequence representing position within the area.
49 . The data structure of claim 47 wherein said coding pattern codes a position sequence representing position of said pattern within the area.
