Computer system equipped with write-only optical disc drive being constructed separately from read-only optical disc drive
First Claim
1. A computer system comprising:
- a computer main body;
a read-only optical disc drive for playing back data recorded on an optical disc, said read-only optical disc drive being provided in said computer main body so as to be able to transmit the data to the computer main body; and
a write-only optical disc drive for writing data to a recordable optical disc, said write-only optical disc drive being constructed separately from said read-only optical disc drive and being provided in said computer main body so as to be able to receive the data from the computer main body wherein each of the disc drives has its own data transmission rate wherein the write-only optical disc drive is unable to read any data recorded on any optical disc.

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.
