ABSTRACT:
An optical disk driving apparatus includes a control computer, and the optical disk driving apparatus acquires a wobble signal. The control computer calculates an average period of a binarized wobble signal and a variance of the period of the binarized wobble signal. The control computer determines whether the calculated average period satisfies the specifications of DVD-R or DVD-RW and determines whether the calculated variance is below a predetermined level.
