Dot code and information recording/reproducing system for recording/reproducing the same
First Claim
1. An optically readable dot code comprising blocks arranged and sized so that a plurality of said blocks fits within a field of view of a reader for scanning the blocks to optically read the dot code, each of the blocks including:
- a data dot pattern comprising a plurality of dots arranged in accordance with contents of information to be recorded,a marker by which the existence of the block is recognized, anda block address pattern representing an address of the block in the dot code,the data dot pattern, the marker, and the block address pattern being arranged in accordance with a predetermined positional relationship within each block;
wherein the address of each block is such that the blocks can be individually identified and the dot code correctly read irrespective of an order in which the blocks are scanned by the reader.

Abstract
A long time optical recording and repeated reproduction of multimedia information is possible. Using a printer system or printing process system, on a recording medium such as a sheet, the so-called multimedia information in the form of dot codes (36) together with images (32) and characters (34) is recorded. The multimedia information includes audio information such as voices, image information obtainable from a camera and others, and digitally coded data obtainable from a personal computer and other. A pen-like information reproducing device (40) is manually moved to scan the dot codes (36) and to take in the dot codes. The original sound is generated by a voice output device (42) such as an earphone, the original image information is outputted on a display such as a CRT, and the digitally coded original data to a page printer or the like.
