英文摘要	A driving voltage of a laser diode provided in an optical disc apparatus is properly set based on an operating environment thereof to reduce unnecessary power consumption and heat generation. A temperature detector detects the temperature inside a pickup. A memory stores a value of the voltage to be supplied to a laser driver, the voltage corresponding to each of various operating environments. A controller refers to voltage values stored in the memory to set the voltage to be supplied to the laser driver based on a current operating environment. Operating environment parameters includes at least one of the temperature, operation mode, recording rate, and accumulated light emission time. The voltage value to be stored in the memory is a value of the voltage at which electric power consumed by the laser driver becomes smallest in the operating environment.
