ABSTRACT:
Method of recording control signals on a removable optically readable disc like recording device comprising recording control data representing the physical structure of an optically readable disc. The control data set either being a standardized set of control data corresponding to the record carrier or either being a non-standardized set of control data deviating form the standardized set of control data signals. Preferably the non-standardized set of control data relates to different values for the number of information layers present on the record carrier or the type of record carrier being of the read-only type, recordable or rewritable type. Preferably a user may select the non-standardized set of control data by selecting a corresponding type of playback and/or recording apparatus.
