摘要

The data record medium is adapted for recording medium information as unerasable data and copy management information. The medium information represents the type of data record medium including at least a read-only type and a write enable type. The copy management information represents whether information data recorded on the data record medium is a copy enable state or a copy prohibition state. The medium information and the copy management information are detected from the data record medium. The information data is read from the data record. The controlling unit for substantially prohibits the reproducing unit from outputting the information data when the medium information satisfies both a first condition representing that the medium information is not at least the read-only type and a second condition representing that the copy management information is the copy prohibition state.
