ABSTRACT:
This optical disk device includes an examination means which examines a first physical characteristic of an optical disk, and a servo means which starts servo control based upon that first physical characteristic. This optical disk device includes a read means which incorporates the examination means, and which reads type information from the optical disk under that servo control based upon the first physical characteristic. This optical disk device includes a control means which decides whether or not a second physical characteristic of the optical disk, which is determined as a standard for the type of type information read, and the first physical characteristic, agree with one another. And, if the control means has decided that these two physical characteristics do not agree with one another, it commands the read means to read replay data from the optical disk, under that servo control based upon the first physical characteristic.
