Abstract
A disk device for recording data onto a disk in accordance with a predetermined layout containing a footer portion. In the disk device, upon receipt of a record command entered by a user, a CPU reads out a TDB of a track finally subjected to data recording, and judges whether or not a data recording method used for the data recording is a track-at-once recording method or a packet-writing recording method. When it is the packet-writing recording method, the CPU reads out the data located at a position precedent to a record start address by two frames, and judges whether or not the mode of the header is Ro1 (bit value=111). When it is any other than Ro1, the CPU judges that the disk rejects the recording of data thereonto, and outputs a message stating that the disk rejects the recording of data thereonto.
