Abstract
According to one embodiment, an optical disk apparatus is provided with a read section which reads data from an optical disk to output read information, a determination section which determines presence/absence of an error of the read information to output an error presence/absence signal, a transfer processing section which receives the error presence/absence signal and receives a hash request signal and transfers the hash request signal when the error presence/absence signal indicates the absence of an error, and does not transfer the hash request signal when the error presence/absence signal indicates the presence of an error, and a processing section which performs hash processing to the read information upon reception of the hash request signal.
