    • When a medium selection button 101 is operated, an optical disc reproduction apparatus 1 recognizes which medium is selected according to inputted medium selection information, and then opens a tray 104. Next, when a medium selection button 101 is operated, the optical disc reproduction apparatus 1 determines the inputted medium selection information and closes the tray 104. Next, the optical disc reproduction apparatus 1 acquires a priority list 16 and modifies the priority list 16 such that the order of the selected medium in the priority list 16 is a first priority and the remaining orders of the other media are successively lowered. The optical disc reproduction apparatus 1 performs a medium check for each of the media in accordance with the orders of the modified priority list 16.
    • 当操作介质选择按钮101时,光盘再现装置1根据输入的介质选择信息识别哪个介质被选择,然后打开托盘104.接下来,当操作介质选择按钮101时,光盘再现设备 1确定输入的介质选择信息并关闭托盘104.接下来,光盘再现设备1获取优先级列表16并修改优先级列表16,使得优先级列表16中所选择的介质的顺序是第一优先级, 其他媒体的剩余命令依次下降。 光盘再现装置1根据修改的优先级列表16的顺序对媒体进行媒体检查。
