| titleOfInvention | Optical recording system and optical recording medium |
| abstract | (57) [Problem] To provide an optical recording medium suitable for multi-level recording. An optical recording medium on which information can be recorded by irradiating a laser beam, wherein a plurality of virtual recording cells of a predetermined length are continuously defined in a relative movement direction of the optical recording medium. 20% of the reflectivity variation range XY defined from the initial reflectivity X of the cell and the minimum reflectivity Y The recording power required to change from the initial reflectivity X by the laser beam irradiation is A, and 80% of the reflectivity variation range XY is changed from the initial reflectivity X by the laser beam irradiation. Assuming that the recording power required for B is B, the recording layer is 1.8 <(BA) / A < Thus, the irradiation power of the laser beam was switched to five or more steps to enable multi-level recording. |
