ABSTRACT:
A mutually and repeatedly reproducible information recording medium, and method for preparing the same, prepared by forming first blocks, adjacent to each other and spaced by space sections, comprising first information on one track of the information recording medium, and forming second blocks comprising second information arranged in the reverse flow direction of information on the other track, so that parts of the other tracks corresponding to the start points of the individual first or second blocks on the one track are always space sections, in which one block of the first or second information is reproduced and, after the reproduction of the block is complete, the information recording medium is run in the reverse direction to reproduce the other track, thereby reproducing the second or first information corresponding to the previously reproduced information.
