The invention relates to an operating system for data media, which enables copy control. The inventive system consists of physical supports comprising a digital data record, standard computer equipment which is used to read and copy one such physical support and recordable duplication supports. The invention is characterised in that the format used to record information on the physical support is determined such as to inhibit the copy functionalities of the standard computer equipment, and in that the system comprises means of modifying the standard computer equipment in order to enable conditional copying of said physical supports, the duplication producing a record which is different from the original record, which is non duplicable.
