Abstract: The invention discloses a method for adjusting the temperature in an optical information reproducing apparatus, including a spindle motor for driving an optical information medium disposed within the optical information reproducing apparatus and a pick-up head unit for retrieving/recording data from/to the optical information recording medium. By the method according to the invention, the temperature in the optical information reproducing apparatus is cooled down by an air flow caused by the rotating optical information recording medium driven by the spindle motor.

Abstract: The present invention discloses a light emitting device power supply circuit, a light emitting device control circuit and an identifiable light emitting device circuit therefor, and an identification method thereof. The light emitting device control circuit includes an operation signal generation circuit and an identification circuit. The operation signal generation circuit determines whether the light emitting device control circuit operates in an identified mode or amiss mode according to an enable signal. In the identified mode, the light emitting device control circuit operates a power stage circuit to supply an output current to an identifiable light emitting device circuit. In the miss mode, an output voltage is maintained at a predetermined level. The identification circuit determines whether the light emitting device control circuit switches from the miss mode to the identified mode according to whether the output voltage meets a condition.
