A recording/reproducing device includes an optical head unit which performs writing and reading of information expressed by marks and spaces on an optical recording medium by irradiating laser light onto the optical recording medium, a laser driving pulse generating unit that generates a laser driving pulse according to the recorded information to supply a laser driving signal to the optical head unit, and executes the irradiation of the laser light onto the optical head unit for recording, an evaluation value calculating unit that calculates a quality evaluation value, which is an index of recording signal quality based on a signal read from the optical recording medium by the optical head unit, and an adjustment controlling unit that performs an adjustment setting of the laser driving pulse generated in the laser driving pulse generating unit.
