The present invention relates to a drive apparatus (20) for accessing an optical record carrier (10) carrying a time-indicative information (T) and a second ROM mark (M2), comprising: —an access unit (21, 25) for accessing said record carrier (10) for reading data from and/or writing data to said record carrier (10), —a time-information detector (D3) for checking for the presence of time-indicative information (T) and for checking, if time-indicative information (T) is present, whether said time-indicative information (T) indicates a time that lies before a predetermined reference time, —a second ROM mark detector (D2) for checking, if said time-indicative information (T) indicates a time that lies on or after said predetermined reference time, for the presence of said second ROM mark (M2), and—a controlunit (23, 24) for controlling said access unit (21, 25) such that the reading and/or writing of data is inhibited if said time-indicative information (T) indicates a time that lies on or after said predetermined reference time, but said second ROM mark (M2) is not present on said record carrier.
