Optical storage system comprising interface for transferring data

An optical storage system for coupling to at least a plurality of peripheral devices. The optical storage system includes a data read subsystem to read out data stored in an optical storage medium, a data process subsystem to generate address information and data information according to the read out data, and an interface controller to generate output data according to the address information and the data information and to transfer the output data to one of the peripheral devices. A number of bits of the output data being transferred in parallel is configurable according to a parallel bit number. The data information and the address information are transferred via the same pins.
