Abstract

PURPOSE:To prevent the unsuccessful relief of a kickback and an excessive off-track by providing a track guide groove in the rotating direction opposite to the rotating direction of a spiral-like track guide groove, and a track guide groove in the same rotating direction, on the outside of the outermost circumference of an additional type optical disk, and the inside of the innermost circumference, respectively. CONSTITUTION:A format decoder 10 detects and discriminates by information from a device part 9 whether an additional track guide groove which has caught an optical disk device 8 is an outside circumferential side additional track guide groove 3 or an inside circumferential side additional track guide groove 4. Subsequently, information is outputted to a microprocessor 6. If a failure of a kickback or an excessive off-track occurs in the outside circumferential side of a track guide groove 1, an optical disk device which has moved through a locus shown by a broken line is caught by the outside circumferential side additional track guide groove 3 and can be returned to a normal locus.

The optical disc includes a disc for exclusive use by students, and additional notes 4 (1, 1).
There are optical discs and old replacement optical discs, but write-once optical disc devices that allow the user to record additional information locally heat the recording medium with a writing laser beam and use a thin film (often Te-based thin blades). Recording is performed by punching holes in the film and changing the reflectance of the film, and reproduction is performed using changes in the intensity of reflected light.
