摘要： An apparatus and method for controlling power of a laser diode (LD) are provided, which allow the power of the laser diode (LD) affecting a performance of an optical recording apparatus to be constantly maintained at an optimum state, regardless of a variation in temperature. The method for controlling power of a laser diode (LD) used for an optical recording apparatus to record data in an optical recording device comprises: a) sampling the LD's power generated when data is recorded; and b) compensating for a variation of the LD's power changed according to sampling locations.
