ABSTRACT:
A servo track formed on a tape-like recording medium is verified. An input unit allows a user to input information. A tape drive unit causes the tape-like recording medium to run on a predetermined route. A measurement unit is provided adjacent to the predetermined route of the tape-like recording medium and configured to detect the servo track on the running tape-like recording medium driven by the tape drive unit, to output a track detection signal. A storage unit stores a plurality of functions each of which is uniquely determinable by the information to be provided through the input unit. 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.
