    • An audio disk/memory disk player. At the time of playing a disk, TOC information in a lead-in area will be read out first after loading of the disk is complete. The player determines whether the disk to be played is an audio disk (CD) or a memory disk (CD-ROM) based on identifying information in the TOC information. If the disk is the memory disk, the operation goes directly to a pause mode so that upon reception of a read command transition to the searching for a designated address is promptly executed to quickly read out the desired data. Only when the disk being played is the audio disk, the audio system is changed to the audio disk from another source, thus permitting a user to view a map while listening to the previous source. When playing for an area having a series of group information recorded is complete in special play mode, the mode is quickly changed to the pause mode in the case of the memory disk to wait for the read command, thus ensuring quick reading of designated map data. If the disk discrimination result indicates the memory disk, a muting process is performed to inhibit a sound generation from a loudspeaker. If in this case there are operation commands originating from erroneous confirmation by the user, at least one of the commands is ignored.
    • 一个音频磁盘/内存盘播放器。 播放磁盘时,导入区域的TOC信息将在装载完成后首先读出。 播放器基于TOC信息中的识别信息确定要播放的盘是否是音频盘(CD)或存储盘(CD-ROM)。 如果磁盘是存储盘,则操作直接进入暂停模式,使得在接收到读取命令时,迅速地执行转换到搜索指定地址以快速读出所需数据。 只有当正在播放的磁盘是音频磁盘时,音频系统才会从另一个源更改为音频磁盘,从而允许用户在收听上一个源时查看地图。 当在特殊播放模式中完成具有一系列组信息的区域的播放时,在存储盘的情况下,模式快速地改变为暂停模式以等待读命令,从而确保快速读取指定的地图数据 。 如果盘识别结果指示存储盘,则执行静音处理以禁止来自扬声器的声音产生。 如果在这种情况下存在由用户的错误确认引起的操作命令,则忽略至少一个命令。
