Abstract: In an optical disk apparatus, when the write-in process to the optical disk is interrupted, a data processing part and an encoder part are set to be in the waiting state after an access to a data storing part is completed, so as to stop accessing the data storing part and also to stop storing data that is to be written. Thus, the interleave can be managed and the DSV calculation can be properly conducted without any irregular calculation. Even in a case in which the write-in process to the optical disk is restarted after temporarily interrupted, it is possible to read data similar to a case in which data to be written is successively written without an interruption.
