An optical recording apparatus obtains the most appropriate recording laser power state in real time according to an environmental mark-generation condition. When data is recorded (mark is generated) by emitting pulse-train-manner laser outputs to an organic-pigment recording medium, a first signal value corresponding to a first pulse in the pulse-train-manner laser outputs and a second signal value corresponding to second and subsequent pulses in the pulse-train-manner laser outputs are detected as a reflected-light information signal; the ratio thereof is obtained; and the obtained ratio and a reference ratio are used to generate a laser-power compensation signal to control the power of the laser outputs.
