ABSTRACT:
An optical disc drive1of the present invention includes an electrically rewritable flash ROM32which stores firmware of the optical disc drive1; means for judging whether or not the loaded optical disc2is a predetermined type of optical disc in which update data for updating the currently stored firmware is stored when the optical disc2is loaded into the optical disc drive1; a buffer memory31for temporarily storing the update data recorded in the loaded optical disc2in the case where the judging means judges that the loaded optical disc2is the predetermined type of optical disc; and control means9for determining whether the currently stored firmware of the optical disc drive1should be updated with the update data based on the absence or presence of a predetermined signal (a signal outputted when an eject button is pushed), and updating the currently stored firmware with the update data stored in the buffer memory31in the case where it is determined that the currently stored firmware of the optical disc should be updated.
