    • The present invention provides an optical disc apparatus that reduces access time while suppressing the emanation of heat from a beam expander. A microcomputer manages the operation time and pause time of a stepping motor constructed to move the movable lens of the beam expander, and in accordance with the duration of an immediately previous pause, limits the number of successive stepping-motor driving actions following the pause time, below a maximum permissible count. When the pause duration is shorter than a threshold value or when the number of successive stepping-motor driving actions reaches the maximum permissible count, the microcomputer starts next driving of the stepping motor after a required waiting time.

    • A disk cartridge is provided in which if the width of the disk cartridge is W1 and the outside diameter of the disk is D1, then W1 is about the same as D1. Inside the disk cartridge is a disk space in which the disk can rotate. A movement restricting portion restricts movement of the disk in the direction parallel with a disk surface. A cutout that extends through into the disk space is provided in part of a surface forming the width of the disk cartridge. A protrusion is provided in the surface adjacent to the surface in which the cutout is provided and at a position near the cutout.
    • 提供一种盘盒,如果盘盒的宽度为W1,盘的外径为D1,则W1与D1大致相同。 磁盘盒内部是磁盘空间,磁盘可以旋转。 移动限制部分限制盘在与盘表面平行的方向上的移动。 在形成盘盒的宽度的表面的一部分中设置有延伸穿过盘片空间的切口。 在与设置有切口的表面相邻的表面中设置有突起,并且位于靠近切口的位置处。

    • A disk is moved between disk cartridges without being in touch with the disk. Therefore, movement of the disk between the disk cartridges is carried out via a disk holder. Further, when the disk is moved between the disk cartridges, disk information of the cartridge is also moved simultaneously. Accordingly, the disk information held by the disk cartridge is provided at a disk holder portion and the disk information can be read by other disk device. Further, the disk holder is provided with a region representing information of the disk. When it is made to be a label region, in moving the disk between the disk cartridges, also the disk information held by the disk holder can simultaneously be moved. Further, even when the disk cartridge incorporates the disk, the content of the disk can easily be recognized via the disk holder. Further, a user can arbitrarily write or erase content of the disk to or from the label region, the disk is recognized easily and easiness of use is considerably promoted.
    • 磁盘在磁盘盒之间移动而不与磁盘接触。 因此,盘之间的盘移动通过盘保持器进行。 此外,当盘在盘盒之间移动时,盒的盘信息也同时移动。 因此,由盘盒保持的盘信息设置在盘保持部,盘信息可由其他盘装置读取。 此外,盘保持器设置有表示盘的信息的区域。 当使其成为标签区域时,在盘之间移动盘片时,也可以同时移动由盘保持器保持的盘信息。 此外,即使当盘盒包含盘时,也可以通过盘保持器容易地识别盘的内容。 此外,用户可以任意地向标签区域或从标签区域写入或擦除盘的内容,容易地识别盘,并且显着地促进了使用的容易性。
