Abstract
In a recording material, physical characteristic information of the recording medium, and more specifically, material information representing the material of the disc, is recorded. Accordingly, a recording apparatus and a reading apparatus easily and accurately determine the physical characteristics of the disc, thereby making it possible to provide suitable setting for performing an operation.
Claims2
A method of recording data to an optical disc, comprising:
- reading predetermined information from a record track formed by a groove on the optical disc, the groove representing at least a target recording power and highest speed code by wobbling of the groove;
- setting a laser power for recording data to the optical disc based on the read target recording power which indicates a target laser power level at high recording velocity;
- and
- setting a recording speed based on the read highest speed code which indicates the highest constant linear velocity recording speed.
