An arithmetic unit is configured to determine an oscillation amount of the servo track from the track detection signal output from the measurement unit, using a function determined on the basis of the information provided through the input unit. The function used for determining the oscillation amount of the servo track is retrievable from among the plurality of functions stored in the storage unit.
