Zusammenfassung:nn An optical disk apparatus for performing ROPC. A controller of the optical disk apparatus detects the quantity of reflected light Bo acquired when OPC is performed to set initial recording power Po; computes recording power P such that Bo/Po=B/Pis achieved in relation to the quantity of reflected light B acquired during recording of data; and computes next recording power Pr by use of a coefficient α by means of Pr=(1−α)·Pc+α·P in relation to current recording power Pc, to thus control recording power. The coefficient α is set to 0
