摘要： A light modulation element of the invention has a plurality of polygonal modulation portions for modulating incident light staggered on arrays. Sides, of each two adjacent portions on different arrays, which are closest to each other are parallel to each other and are not perpendicular to the array direction. The modulation portions can be arranged at a high density along the array direction, the utilization efficiency of illumination light is improved, and the modulation light amount can be increased. When an element is used for a recording apparatus, and S/N ratio is improved, uniform exposure along the array direction is achieved, and the required memory capacity is decreased. A light modulation apparatus of the invention has an imaging optical system, a modulation optical system, and a scanning optical system. By incorporating a suitable means in an optical system or changing the optical system arrangement, a separation angle between modulated and non-modulated lights is increased, and diffracted light generated due to a shape of a light modulation element as a component of the apparatus can be eliminated.

摘要： An information recording/reproducing apparatus uses a card-like recording medium having an area for information recording and a blank area, the area for information recording having a reflectivity different from that of the blank area. The apparatus includes a head unit for performing at least one of recording and reproduction, an autotracking servo, a stepping motor and the like cooperating to cause the card to reciprocate relative to the head unit, and an abnormal state detect circuit for detecting whether the card is inserted in the apparatus in a normal state. The abnormal state detect circuit includes a photosensing unit consisting of a light-emitting element for emitting light rays onto the card and a light-receiving element for receiving the light rays from the card. The photosensing unit is deviated with respect to a central portion of the card along a direction perpendicular to a reciprocal movement of the card so that the area for information recording is irradiated with the light rays from the light-emitting element upon insertion of the card in the normal state.
