A recording apparatus includes an optical head recording information by irradiating laser light onto an optical recording medium; a laser power control circuit controlling the power of laser light output from the optical head on the basis of a target value of laser power and a monitor signal of the laser power detected by the optical head; and a target-value varying circuit detecting amplitude variations of a light quantity signal of return light of the laser light irradiated onto the optical recording medium and varying the target value on the basis of the amount of the detected amplitude variations.
