1. A multi-functional optical disk driving device, used for personal computer (PC), which has functions of a compact-disk (CD) driver, a digital versatile disk (DVD) driver, a frequency modulated (FM) radio, a MP3 music CD player, said device comprises:

  • a multi-functional vision process controller (VPC) with a PC power on status detector, a microprocessor, an optical disk server;

    a bus switch, connected between standard interfaces of the PC and the optical disk server, and a microprocessor, for control of on/off of the bus switch, characterized in that said vision process controller (VPC) can disconnect the standard interfaces between said PC and said optical disk server by means of controlling the bus switch via said microprocessor when the PC is off, and the microprocessor performs the above functions independent; and

    said microprocessor controls said bus switch to connect the standard interfaces between said PC and said optical disk server when PC power on state is detected by the PC power on status detector, and the above functions are performed by said PC.
