PURPOSE: An optical disk driving device and a driving method, a recording medium and a program used with the recording medium are provided to obtain a wobble signal to operate an average section of the wobble signal and a variance of a wobble signal section, and to decide a type of an optical disk based on the average section and the variance, thereby identifying the disk type without an additional identifier device. CONSTITUTION: An optical disk recording/reproducing device(1) drives an optical disk(2), and reads data recorded on the optical disk(2) to record or reproduce data on the disk(2). A signal generator(14) generates a control signal based on a signal supplied from an optical pickup(11), and provides the control signal to a main controller(16). The signal generator(14) generates a demodulation signal based on the provided signal, and supplies the demodulation signal to a signal processor(15). When data is recorded on the disk(2), the signal generator(14) creates a recording signal, and provides the recording signal to the optical pickup(11).
