    • Disclosed is a disc drive apparatus. The disc drive apparatus includes a rotational driving unit rotating a disc-shaped recording medium having a plurality of addresses recorded on an information recording surface of the disc-shaped recording medium; an optical pickup recording and/or reproducing an information signal on the information recording surface of the disc-shaped recording medium rotated by the rotational driving unit; and a control unit controlling rotation of the disc-shaped recording medium via the rotational driving unit. In the disc drive apparatus, the control unit carries out a disc constant velocity rotating processing that sets a predetermined address out of the plurality of addresses as a constant velocity rotation address and continuously reproduces the constant velocity rotation address using the optical pickup.
    • 公开了一种盘驱动装置。 盘驱动装置包括旋转驱动单元,其旋转具有记录在盘形记录介质的信息记录表面上的多个地址的盘形记录介质; 在由旋转驱动单元旋转的盘状记录介质的信息记录表面上记录和/或再现信息信号的光学拾取器; 以及控制单元,其经由旋转驱动单元控制盘状记录介质的旋转。 在盘驱动装置中,控制单元执行盘定速旋转处理,其将多个地址中的预定地址设置为恒速旋转地址,并使用光学拾取器连续地再现等速旋转地址。

    • A disc drive apparatus includes: a rotational driving unit rotating a disc-shaped recording medium; a recording and/or reproducing unit recording and/or reproducing an information signal on the information recording surface of the disc-shaped recording medium; a print head printing visible information onto a label surface of the disc-shaped recording medium; and a pulse signal generating unit detecting rotation of the rotational driving unit and generating a pulse signal. Further, the apparatus includes a signal processing unit generating a specified address signal where a pulse is generated when a specified address on the disc-shaped recording medium is reproduced; and a control unit carrying out, based on the pulse signal and the specified address signal, disc correlating processing correlating a disc base position where the specified address is recorded on the disc-shaped recording medium and the pulse signal to obtain position information for the disc-shaped recording medium from the pulse signal.
