Method of managing the copying of contents-representing data

摘要

In a method of managing the copying of data representing contents, contents and a copyright number given from a copyright holder to the user regarding the contents are sent to a user as virtual contents files whose number is equal to the copyright number. In cases where the user copies the contents from a source recording medium to a destination recording medium, the virtual contents files are moved from the source recording medium and are erased therefrom.
