Abstract
The present invention suppresses a data writing speed in mirroring and increases expandability. For a write request from a host, a disk controller stores write data in cache memory, and then transforms it into optical signals by a light emitting apparatus and sends them to an optical bus. The signal light inputted to the optical bus is broadcast-transmitted by the optical bus and read into disk drives simultaneously through a light receiving apparatus. This suppresses reduction in a data writing speed in mirroring and increases expandability.
