    • 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.

    • 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.
    • 一种光信息记录/再现装置,它被设置在聚焦伺服被驱动的状态下,记录在记录介质上的跟踪误差信号或光电检测器的和信号是从被引导到光电探测器上的一根光线产生的。 然后,测量跟踪误差信号的信号幅度或光电检测器的和信号。 接下来,大致校正记录介质和物镜之间的相对倾斜,直到信号幅度达到预先确定的阈值。 在粗略校正之后,在预定轨道上驱动跟踪伺服的状态下,对预定轨道执行跟踪,检测倾斜检测信号,并基于以下方式精细地校正记录介质和物镜之间的相对倾斜 倾斜检测信号。
