ABSTRACT:
On an information recording medium, multimedia information including at least one of audio information, image information, and text data is recorded as an optical readable code. The code is constituted by arranging a plurality of blocks, and each block has a data dot pattern including a plurality of dots arranged in correspondence with the data contents, and a marker which is arranged to have a first predetermined positional relationship with respect to the data dot pattern and determines a reference position required for reading the data dot pattern. The dots of the data dot pattern and the markers are recorded on the information recording medium so that the dots, the markers, and the information recording medium have different predetermined reflectances or transmittances. More specifically, in order to reduce code redundancy, the dot code is recorded as follows. If the information recording medium is white, markers are recorded as black dots on the information recording medium, and pattern, address, and data dots are recorded so that data "1" are expressed by gray dots and data "0" are expressed by transparent dots. With this format, the markers and dots are recorded to have the same size. In this case, the data dots are not modulated. An information reproducing system reproduces a code recorded on the information recording medium, and a marker/dot separation processing unit separates markers and dots using two different threshold values.
