US Patent 7965588 Optical disk apparatus

An optical disk apparatus includes an I/O port that connects to a port of a drive apparatus, and a storage unit that prestores manufacturing information in correspondence with device drivers. The optical disk apparatus further includes a controller that transmits a command indicating to return manufacturing information, to the drive apparatus via the I/O port. When manufacturing information is returned from the drive apparatus via the I/O port, the controller extracts a device driver corresponding to the returned manufacturing information from the device drivers in the storage unit. The controller then controls a reading operation or a recording operation of the drive apparatus on the optical disk, based on the extracted device driver.
