PROBLEM TO BE SOLVED: To improve recording accuracy.SOLUTION: An optical recording device 100 records information in an optical information recording medium 118 by irradiating the optical information recording medium 118 with signal light and reference light modulated by a spatial light modulator 110 using a liquid crystal cell. The optical recording device 100 also converts, into an electric signal, reproduction light obtained by irradiating the optical information recording medium 118 with the reference light using an image pick-up device 121. An adjustment unit 122 adjusts the temperature of the spatial light modulator 110. A storage unit 124 stores control conditions that are selected based on control conditions of the adjustment unit 122 and on the electric signal obtained by the image pick-up device 121. A control unit 123 controls the adjustment unit 122 according to the control conditions stored in the storage unit 124. |
