This control board is composed of a directory development processing station, various types of interface processing stations, a retrieval processing station, a data transfer/receiving processing station, a data input/output processing station and a directory update processing station. It is possible to have access as easily to the optical recording medium as to other existing media by using commands, I/O functions, and so on in the computer body. Furthermore, compared with access to the optical recording medium read/write device by only use of software installed in the computer body, the burden on the computer body is reduced in connection with memory size and processing time.
