Optical disk driving apparatus and method, and recording medium and program used therewith
摘要:
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.
