ABSTRACT:
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.
