Abstract
A method for writing data to and reading data from an optical disk that has address information written on its land between grooves or in its pregrooves. Because data is written to and read from the pregrooves or land where no address is written, continuous signals can be written to and read from the disk without format change. Further, the data area is widened by the amount of the nonexistent address area.
