본 발명은 2종류의 매체의 겸용장치를 호스트에 대하여 독립한 드라이브, 예를 들면 CD 플레이어 및 MO 드라이브로서 보고, 디바이스드라이브용 OS에의 정합성을 높이기 위한 것이다. 그 구성은 호스트(370)의 호스트인터페이스에 있어서의 고유의 ID 번호인 마스터와 슬레이브의 할당을 받고, MO용 코멘드의 수신과 응답을 행하는 MO용 제1호스트인터페이스회로(314)와, CD용 코멘드의 수신과 응답을 행하는 CD용 2호스트인터페이스회로(326)를 설비한다. A first host interface circuit for an MO and a second host interface circuit for a CD are provided in order to allowing a common apparatus of two kinds of medium to be seemed as independent drives, for example, a CD player and an MO drive for a host. The first host interface circuit for the MO and the second host interface circuit for the CD are allocated to a master and a slave by peculiar ID numbers in a host interface. The first host interface circuit for the MO executes a reception of a command for the MO from and a response to the host interface. The second host interface circuit for the CD executes a reception of a command for the CD from and a response to the host interface.
