Optical disc drive and method of updating firmware

Abstract

An optical disc drive 1 of the present invention includes an electrically rewritable flash ROM 32 which stores firmware of the optical disc drive 1; means for judging whether or not the loaded optical disc 2 is a predetermined type of optical disc in which update data for updating the currently stored firmware is stored when the optical disc 2 is loaded into the optical disc drive 1; a buffer memory 31 for temporarily storing the update data recorded in the loaded optical disc 2 in the case where the judging means judges that the loaded optical disc 2 is the predetermined type of optical disc; and control means 9 for determining whether the currently stored firmware of the optical disc drive 1 should 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 memory 31 in the case where it is determined that the currently stored firmware of the optical disc should be updated.
