A compatibility engine 28 arranged to be interfaced with an optical pickup unit 16 of an optical disc drive 12 and operable to manage a read by the optical pickup unit of embedded compatibility information 18, 30 from an optical medium 14. The compatibility information embedded in an optical medium modifies actions allowed by predetermined non-compatible optical disc drives on the optical medium where the optical disc drives may suffer damage if certain actions are performed on the optical medium. For instance, a compatibility engine of the optical disc drive applies compatibility information read from an optical medium to determine restrictions to impose on the use of the optical medium, such as restricting the optical disc drive from writing to the optical medium, reading from the optical medium or performing any operations until an update to the optical disc drive firmware is performed either automatically or by display of a compatibility user interface 48 at an information handling system 10 associated with the optical disc drive. In one embodiment, the compatibility information identifies incompatible optical disc drives and firmware versions. |
