摘要： The invention provides an optical disk system having at least: an optical disk comprising, on a substrate having pre-pits, an image-recording layer capable of drawing an image by irradiating a laser light; and a reading device which reads information included in the pre-pits by a return light of the laser light when the laser light having a wavelength of in a range of 630 to 680 nm is irradiated to the pre-pit of the optical disk. The pre-pits have a shortest pit length in a range from 0.6 to 0.9 µm being formed on the substrate. The invention further provides an optical disk recording apparatus, an image drawing method and an optical disk which utilize the optical disk system.
