Abstract
An optical recording medium has a plurality of layers of recorded information including at least digital data of picture, music, or computer software in a form of recorded marks or pits readable by optical means. The digital data is divided into a plurality of data groups, each group being smaller than a recordable capacity of each layer, and the divided data groups are distributed among the plurality of layers so that an original digital data become discontinuous within each layer.
