Abstract
A servo adjustment apparatus for setting an adjustment value for servo control of at least one of optical recording of information on information recording surfaces and optical reproduction of information recorded on the information recording surfaces, is provided. A setting device sets an adjustment value corresponding to one of the information recording surfaces. Another setting device sets another adjustment value corresponding to another one of the surfaces other than the one of information recording surfaces. Then a calculation device calculates a relational value indicating a relationship between the adjustment value and another adjustment value. A storage device stores calculated relational value. A resetting device resets the adjustment value using another adjustment value set previously and the relational value when the adjustment value is reset, and resets another adjustment value using the adjustment value set previously and the relational value when another adjustment value is reset.
