Abstract
A system wherein management data for managing allowance or unallowance (i.e., prohibition) of copies on a recording medium are recorded, and a time restriction condition, an area limiting condition, a condition for restricting a copy mode, etc. are managed on the basis of the recorded copy management data. When data are copied to different recording media, the copy management data are recorded together with the main data, thereby restricting the reproducing operation of the main data.
