    • An optical disk device of the present invention includes a spindle motor, an optical pick-up, and a rotation control portion. The spindle motor is a rotational drive portion that rotates an optical disk, on an information recording surface of which a plurality of addresses are recorded. The optical pick-up records an information signal onto and plays back the information signal from the information recording surface of the optical disk that is rotated by the spindle motor. The rotation control portion controls the rotation of the optical disk by the spindle motor. In this case, the rotation control portion performs control based on a first reference signal that can be read off the optical disk, such that the optical disk is rotated at a speed that is based on a specified clock count.
    • 本发明的光盘装置包括主轴电动机,光学拾取器和旋转控制部。 主轴电动机是在记录有多个地址的信息记录表面上使光盘旋转的旋转驱动部。 光学拾取器将信息信号记录在由主轴电动机旋转的光盘的信息记录表面上并重放信息信号。 旋转控制部通过主轴电机来控制光盘的旋转。 在这种情况下,旋转控制部分基于可以从光盘读出的第一参考信号进行控制,使得光盘以基于指定时钟计数的速度旋转。

    • A printing apparatus includes a printing unit for printing visual information on a non-recording surface of a rotatably driven recording medium by discharging ink droplets. A control unit controls movement of the printing unit in a radial direction of the recording medium, and discharge timing of the ink droplets. The printing unit prints the visual information by multi-path printing by printing on a same radius position of the non-recording surface by discharging ink from different ink discharge nozzles. The control unit controls the printing unit so as to print with a first printing pattern having a first number of paths and a second printing pattern having a second number of paths. The first printing pattern is used on other locations of the non-recording surface and the second printing pattern is used when printing on an innermost periphery region of the non-recording surface.
    • 一种打印装置,包括一个打印单元,用于通过排放墨滴在可旋转驱动的记录介质的非记录表面上打印视觉信息。 控制单元控制打印单元沿记录介质的径向的移动,以及墨滴的排出定时。 印刷单元通过在不记录表面的相同半径位置上通过从不同的喷墨喷嘴排出墨来通过多路径打印来打印视觉信息。 控制单元控制打印单元,以便以具有第一数目的路径的第一印刷图案和具有第二数量的路径的第二印刷图案进行打印。 第一印刷图案用于非记录表面的其它位置,并且当在非记录表面的最内周边区域上打印时使用第二印刷图案。
