    摘要： An image forming apparatus has an image forming unit and a feeding unit for feeding a recording material at a predetermined speed to the image forming unit. A reflective type sensor reads irradiated light reflected off of the recording material and an image reading unit reads the light so as to obtain a surface image of the recording material so that a feed control unit can control the feeding of the recording medium so that a moving distance is shorter and in the case of feeding it at a predetermined speed while the recording material is read by the image reading unit. In the image forming apparatus a reflective type determination unit determines a predetermined attribute of the recording material using the surface image of the recording material read by the image reading unit so that the image forming apparatus can determine a kind of recording material based on the attribute obtain so as to form the image on the recording material.

    摘要： Provided is an optical information recording/reproduction apparatus in which a tilt margin in a radial direction of an optical disk is increased to thereby reduce a danger that the optical disk and a solid immersion lens come into contact with each other as compared with a conventional case. The optical information recording/reproduction apparatus of the present invention includes: an objective lens for condensing a light beam from a light source; and a solid immersion lens (SIL) that is disposed between the objective lens and an optical recording medium, in which a shape of a bottom surface of the SIL on a recording medium side of the SIL is formed such that a length of the bottom surface in a radial direction orthogonal to a track direction of the recording medium is shorter than a length of the bottom surface in the track direction.

    摘要： An optical information recording/reproducing apparatus and are provided under a state where a focus servo is driven, a tracking error signal recorded on the recording medium or a sum signal of a photodetector is generated from a pencil of light guided onto the photodetector. Then, the signal amplitude of the tracking error signal or the sum signal of the photodetector is measured. Next, the relative tilt between the recording medium and the objective lens is roughly corrected until the signal amplitude reaches a threshold value determined in advance. After the rough correction, under a state where a tracking servo is driven on a predetermined track, tracking is performed on the predetermined track, detecting a tilt detection signal, and the relative tilt between the recording medium and the objective lens is finely corrected based on the tilt detection signal.
