ABSTRACT:
A disk which is rotated at one of a plurality of rotation speeds to record information is used. This disk includes a data area formed spirally or concentrically with a center of rotation, in which information is recorded when the disk is being rotated at the rotation speed and a replacement area formed spirally or concentrically with the center of rotation of the disk on a side farther to the center of rotation of the disk than the data area, in which, upon detecting a write error in the data area during rotation of the disk at the rotation speed, information indicating generation of the write error is replaced and recorded at the rotation speed.
