When an optical disc apparatus of the present invention writes to an optical disc, it detects the level of the drive voltage for its laser drive circuit and, based on the detected level, adjusts the drive voltage for its laser diode so as to adjust the drive voltage for the laser drive circuit to a level within an appropriate range. Further, the write speed is also adjusted in accordance with the above adjustment of the drive voltages for the laser drive circuit and the laser diode.
