    • A portable audio system includes a compact disc drive (12) and a control unit (14) communicable through a communication interface (18). The control unit (14) includes a user interface (20), a processing means (22), memory (24), and an audio output (26). The control unit (14) is detachable from the compact disc drive (12), and is operable while disconnected from the compact disc drive (12). The processing means (22) of the control unit is configured to read data from a compact disc within the compact disc drive (12). The processing means can encode the data into digitally formatted files, and store the files within the memory (24) of the control unit (14) while the control unit (14) is connected to the compact disc drive (12). The processing means (22) can read, encode, and store the data at a rate equal. to or faster than the normal rate of play of the data. The processing means (22) of the control unit can produce an audio signal representative of the data in one of the files stored within the memory regardless of whether the control unit (14) is connected to the compact disc drive (12).
    • 便携式音频系统包括可通过通信接口(18)通信的小型光盘驱动器(12)和控制单元(14)。 控制单元(14)包括用户界面(20),处理装置(22),存储器(24)和音频输出(26)。 控制单元(14)可从光盘驱动器(12)拆卸,并且在与光盘驱动器(12)断开连接的同时可操作。 控制单元的处理装置(22)被配置为从光盘驱动器(12)内的光盘读取数据。 处理装置可以将数据编码为数字格式的文件,并且在控制单元(14)连接到光盘驱动器(12)的同时将文件存储在控制单元(14)的存储器(24)内。 处理装置(22)可以以相等的速率读取,编码和存储数据。 达到或超过正常播放速率的数据。 无论控制单元(14)连接到光盘驱动器(12),控制单元的处理装置(22)都可以产生代表存储在存储器内的一个文件中的数据的音频信号。
