PROBLEM TO BE SOLVED: To provide an optical disk device that can record and read out effectually without the effect of an offset value or a laser output value set at starting time even if the temperature in the device changes according to the change of ambient temperature in the optical disk device. SOLUTION: When a temperature is measured by a temperature sensor 12 installed in a pickup 10 and the temperature change is larger than the predetermined value, resetting of an offset value in a focus offset, an offset values in a tracking offset and a laser output value to be outputted from a pickup 10 are made. |
