    • Disclosed is an optical disk handling system, called an autochanger, having two control systems to provide the six motions necessary to move optical disk cartridges from storage holding cells to an optical drive. The system uses shaft encoders on two motors of the two control systems, and current or voltage feedback from the motors, for all positioning, and for detecting the location of the mechanisms during, and at the end of, moves. An optical drive interface connects the electronics of the autochanger and the optical drive, and includes electrical signals to emulate an eject pushbutton on the optical drive and an indicator lamp on the optical drive. The autochanger monitors the on and off state of the lamp signal as well as the duration of the on and off cycles to determine which operation is being performed by the optical drive. The autochanger uses the lamp signal and the eject signal to control all operations with the optical drive.
    • 公开了一种称为自动转换器的光盘处理系统,具有两个控制系统,以提供将光盘盒从存储保持单元移动到光驱动所需的六个运动。 该系统在两个控制系统的两个电动机上使用轴编码器,以及来自电动机的电流或电压反馈,用于所有定位,并用于在移动期间和结束时检测机构的位置。 光驱接口连接自动转换器的电子部件和光驱,并包括电信号,以模拟光驱上的弹出按钮和光驱上的指示灯。 自动转换器监视灯信号的开和关状态以及开和关周期的持续时间,以确定光驱正在执行哪个操作。 自动转换器使用灯信号和弹出信号来控制光驱的所有操作。
