摘要： An information recording medium for suppressing the interferences of bits before and after reproduction and improving the optical resolution with saturable absorber 102 disposed adjacent or in an information recording medium layer 103. The recorded information is detected only from a region having a predetermined optical intensity or more of the focused spot so that minute information bits smaller than the optical resolution can be reproduced to improve the recording density of an optical disk drive drastically.

摘要： An information recording medium includes an information recording layer on which at least information is to be recorded by irradiating light, and a light transmission restricting layer which has a plurality of nonlinear transmission characteristics or nonlinear reflection characteristics for the intensity of the light irradiated and which has an optical material for restricting the transmission or reflection of the light according to the respective characteristics when the light is irradiated onto the information recording layer. An information recording and reproducing unit uses the information recording medium and includes an information recording position setting unit for deciding a position at which information is to be recorded on the information recording medium by detecting a direction of an easy magnetization axis. With the above arrangement, the spot diameter of the light can be distinguished between the one when information is reproduced and the one when information is recorded on the information recording medium respectively, to thereby ensure an accurate positioning of the head on the tracks of the recording medium.

摘要： An optical information processing apparatus comprising a diffraction grating for producing a zero-order beam which is a beam emitted by a light source and allowed to pass therethrough and two plus and minus first-order sub-beams respectively having positive and negative astigmatisms, radiated in directions at slight angles different from the main beam, wherein said two sub-beams are focused at opposite positions across said main beam, wherein focusing control is performed by a focusing error signal detected from a difference of signal amplitudes obtained from the respective reflected light quantities of said two sub-beams and wherein tracking control is performed by an off-track signal obtained from a signal according to a reflected light quantity of said main beam. In an apparatus for magneto-optically reproducing information, above all else, a wave plate is inserted between the focusing lens and the separating optical system, thereby increasing the reflected light quantities and stabilizing the magneto-optical signal, focusing signal and tracking signal.

摘要： In an optical head, light from a semiconductor laser is directed through a condensing optical system with a condensing lens onto an optical information recording medium through a transparent substrate in the form of a light spot. A unit for producing a light spot position control signal and a unit able to move the light spot, which supports the objective lens for movement, position the light spot on an information track. Light reflected from the optical information recording medium is directed through a polarized light branching element to a photo detector. Also mounted for movement with the objective lens are a polarization conversion element, arranged between the optical information recording medium and the polarized light branching element in order to change the polarization state of light incident to the optical information recording medium and reflected therefrom and a polarization diffraction grating, the diffraction efficiency of which changes depending on the change in the polarization state of the incident light and the reflected light caused by the polarization conversion element. The light spot control signal is detected from both reflected light diffracted through the polarization diffraction grating and non-diffracted reflected light contained in the light which passes through the polarized light branching element.
