ABSTRACT:
A computer system comprises a computer main body including a main board on which various components such as a CPU and the like are mounted and a hard disc unit; a read-only optical disc drive provided in the computer main body; a write-only optical disc drive which is constructed separately from the read-only optical disc drive, the write-only optical disc drive being provided in the computer main body; and a bus for connecting the main board, the hard disc unit, the read-only optical disc drive, and the write-only disc drive with each other, in which the hard disc unit, the write-only optical disc drive and the read-only optical disc drive are connected by means of a cascade connection. According to the computer system, it is possible to add a data writing function to a computer system equipped with an existing read-only optical disc drive having a high data transmission rate without increasing a manufacturing cost, thereby enabling to provide a computer system which is easy to use and can be manufactured at a low cost.
