Abstract
A contents managing method of regulating a number of copied contents storable on a storage medium includes giving a predetermined number of copyable contents for each content, recording the copied contents on the storage medium upon reception of an instruction for copy recording on the storage medium when there is a remainder in the number of copyable contents, decrementing the number of copyable contents by “1” every time one copied content is recorded on the storage medium at a time of recording, and incrementing the number of copyable contents by “1” every time one copied content is erased from the storage medium upon reception of an instruction to erase the copied contents from the storage medium.
