Abstract: PURPOSE: To enable the writing of a recording pit finer than the diffraction limit of reproducing light by together using a saturable absorbing dye showing saturable absorbability at the wavelength of reproducing light and a recording dye performing recording by the irradiation with recording light having a wavelength shorter than the aforementioned wavelength. CONSTITUTION: Laser beam with a wavelength λ1 for reproduction is allowed to be incident on an optical recording medium through an optically transparent substrate 1 to be absorbed by an ultra-high resolving power layer 12A containing a saturable absorbing dye. Whereupon, a spot center part high in intensity of laser beam LD permits beam to almost transmit by saturable absorption and reflectivity is enhanced. Therefore, the spot diameter of laser beam becomes smaller than a usual one and the difference of reflection quantity due to the pit 13 formed by irradiating a recording layer 12B containing a recording dye with laser beam with a wavelength λ2 . and the reflecting layer 14 with an area other than that can be read. By this constitution, the writing of a recording pit finer than the diffraction limit of reproducing beam becomes possible.

Abstract: PURPOSE:To make it possible to largely take a reflectivity difference by presence or absence of pits and to execute signal reproduction at high C/N with decreased errors. CONSTITUTION:This optical recording medium of a reproduction-only type is constituted by forming a reflection layer 4 on a substrate 1 formed with the pits 5 as ruggedness with the arranging patterns corresponding to information signals. This optical recording medium for super-resolution reproduction is further constituted by forming a material film 3 having the optical constant changing with photoirradiation or temp. rise between the substrate 1 and the reflection layer 4 in addition to the constitution described above. The pits 5 of the optical recording medium described above are formed to such shapes which are shorten in the length in the scanning direction of a reproducing light spot than the length in a direction orthogonal therewith. Then, the recording information quantity of, for example, about 4 times the present recording information quantity is stored in the optical recording medium of the same size without applying a drastic change, such as shortening of the wavelength of the reproduced light, increasing of the numerical aperture NA of a focusing lens or changing of a signal demodulation system, to the device side.
