摘要： A multi-loaded disk drive arrangement comprises a disk table for holding a plurality of disks arranged on the same circumference thereof, a loading mechanism for rotating the table to move a desired disk so that it is placed at a desired position, and a movement mechanism for moving an optical pick-up located below the table so that it is placed at a predetermined position and a single drive source. This arrangement further comprises a reduction mechanism connecting the loading mechanism and the movement mechanism, a cam wheel for moving upward and downward the optical pick-up by the cam surface formed in an inclined manner on the outer circumferential surface, and a clutch mechanism including an idler adapted to rotate when the idler comes into contact with an inner toothed gear of the disk table, wherein when the idler is located at the position of the toothless portion of the loading mechanism, the idler comes into contact with the inner toothed gear by the drive motor to rotate the disk table in a clockwise direction or in a counterclockwise direction, while when the idler is meshed with the toothless portion, the cam wheel connected to the idler is driven to move the recording/reproducing unit so that it is placed at a recording/reproducing position to stop the drive source.
摘要翻译：一种多重装载的磁盘驱动器装置，包括用于保持布置在同一圆周上的多个磁盘的磁盘台，用于旋转工作台以移动所需磁盘使其位于期望位置的装载机构，以及移动机构用于移动位于桌子下方的光学拾取器，使得其被放置在预定位置和单个驱动源。该装置还包括连接加载机构和移动机构的减速机构，用于通过在外周面上以倾斜方式形成的凸轮表面向上和向下移动光学拾取器的凸轮;以及离合器机构，惰轮适于当惰轮与盘台的内齿齿轮接触时旋转，其中当惰轮位于加载机构的无齿部分的位置时，惰轮通过内齿轮与内齿轮接触驱动马达以顺时针方向或逆时针方向旋转盘台，而当惰轮与无齿部分啮合时，连接到惰轮的凸轮被驱动以使记录/再现单元移动用于停止驱动源的记录/重放位置。
