摘要： An optical head device includes: an optical element collecting light reflected from a reproduction information layer (a target information layer in an optical information recording medium) and light reflected from information layers adjacent to the reproduction information layer at different positions; a light receiving element obtaining a detection signal from the reflected light collected by this optical element; and arithmetic circuitry obtaining a reproduction signal from this detection signal. The light receiving element includes: a first light receiving portion detecting a first detection signal from light containing the light reflected from the reproduction information layer; a second light receiving portion detecting a second detection signal from light reflected from a first adjacent information layer located more distant from the condensing lens than the reproduction information layer; and a third light receiving portion detecting a third detection signal from light reflected from a second adjacent information layer located closer to the condensing lens than the reproduction information layer. The arithmetic circuitry uses constants K and L determined depending on spaces between the reproduction information layer and the adjacent information layers, so as to subtract the K-times second detection signal and the L-times third detection signal from the first detection signal.

摘要： An information recording medium is provided that includes a recording portion (3), which is irradiated with a recording light or a reproducing light so that information is recorded or reproduced thereto or therefrom. The recording portion (3) contains a first phosphor and a photon-mode photosensitive material. The first phosphor has a property of absorbing a first light having a wavelength of λ1/n and then emitting a second light having a wavelength longer than that of the first light, where λ1 is a wavelength of the recording light. The photosensitive material absorbs the second light and then exhibits a change in an optical constant thereof. A n-photon absorption sensitivity of the first phosphor with respect to the recording light is greater than a n-photon absorption sensitivity of the photosensitive material with respect to the recording light, where n is an integer not less than 2.

摘要： A transmission diffraction grating body including a base material being substantially transparent with respect to wavelength λ1 and having a refractive index n0; another base material being substantially transparent with respect to wavelength λ1 and having a refractive index n1, which is formed on the base material having a refractive index n0; and a relief diffraction grating formed on the base material having a refractive index n1; wherein the refractive indexes n1 and n0 satisfy the relationship: n1>n0. Thus, the base material having a refractive index n1 can be formed of a high refractive index material, and when the depth of grating of the diffraction grating is set so that the diffraction grating diffracts the light with wavelength λ1 and does not diffract the light with wavelength λ2, the depth of grating of the diffraction grating can be made to be shallow, thus preventing the loss of the amount of the light with wavelength λ1. Furthermore, since base materials each having a different refractive index are bonded to each other to form a diffraction grating body, it is possible to minimize the use amount of the relatively expensive material having a high refractive index. Furthermore, since the most of the diffraction grating body can be formed of a material having a low refractive index, it is possible to lower the height of the diffraction index body.
