Patent ID: 8520485

Claim:
A recording apparatus comprising: a recording light source configured to emit pulse laser light for recording; a first light source configured to emit first continuous wave laser light; an irradiation optical system configured to irradiate an optical recording medium with the pulse laser light and the first continuous wave laser light via an objective lens in the state in which an optical axis of the first continuous wave laser light is tilted with respect to an optical axis of the pulse laser light; a reception optical system configured to output, to a first light receiver, a returned light portion of the first continuous wave laser light which has been reflected by a reflection surface formed on the optical recording medium and which has been input through the objective lens; a focus servo controller configured to perform focus servo control for the objective lens on the basis of a first reception signal obtained by the first light receiver; a reference-surface-servo light source configured to emit reference-surface-servo laser light having a wavelength different from a wavelength of the pulse laser light or the first continuous wave laser light; and a reference-surface-servo optical system configured to output the reference-surface-servo laser light to the objective lens and to output, to a reference-surface-servo light receiver, a returned light portion of the reference-surface-servo laser light which has been reflected by a reference surface and which has been input into the objective lens, the reference surface being different than one or more reflection surfaces that are recording surfaces of the optical recording medium.
