The circuit interfaces the CD-ROM Driver and one or more computers. The circuit has the selecting function of the driver from the multi- driver system for processing the extra large data. The circuit comprises the 1st and 2nd gate circuits (300a, 300b) generating the function and the control signals by accepting the input output of an unit (200), an output unit (400) selecting the CD-ROM, an I/O buffer circuit (600) writing the function or instruction data for the data transmission direction, and a CD-ROM driver.
