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.

Système informatique comprenant un corps principal constitué d'une carte principale sur laquelle divers composants tels qu'un CPU sont montés, et d'une unité de disque dur; une unité de disque optique pour lecture seule faisant partie dudit corps principal; une unité de disque optique pour écriture seule faisant partie dudit corps principal mais construite séparément de l'unité de disque optique pour lecture seule; et un bus pour connecter les uns aux autres la carte principale, l'unité de disque dur, l'unité de disque optique pour lecture seule, et l'unité de disque pour écriture seule, ces trois derniers éléments étant raccordés entre eux en cascade. Il est possible d'ajouter une fonction d'écriture de données à un système informatique déjà équipé d'une unité de disque optique pour lecture seule à débit binaire élevé sans augmenter le coût de fabrication, ce qui permet d'offrir un système informatique facile à utiliser et de fabrication peu coûteuse.
