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.
Claims6
A recording/reading method for performing at least one of a recording operation and a reading operation on a recording medium, the recording medium including a material information code recorded thereon, the material information code identifying a material of a recording layer of the recording medium, the recording/reading method comprising the steps of:
- rotating the recording medium;
- applying laser light to the recording medium;
- detecting light reflected by the recording medium;
- determining physical characteristics of the recording medium by reading the material information from the reflected light, wherein the material information code identifies the material of the recording layer of a non-registered recording medium;
- and
- performing a setting for the recording operation according to the physical characteristics determined by the determining mechanism, and for allowing the recording operation to be performed.
