Abstract
A control board connected to a main body of a computer, which has access to an optical recording medium through an optical recording medium read/write device, and for controlling and enabling the optical recording medium read/write device to have access to the optical recording medium in the same manner as an existing magnetic disk device and the like have with respect to a magnetic medium. 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.
