Abstract

PURPOSE:To realize control without necessitating the change of software of a host system consisting of a RAM disk (RD) device or a storage device of combination type of a floppy disk (FD) and the RAM disk, by switching a controller circuit. CONSTITUTION:The titled device is constituted in such a way that first and second multiplexers 4 and 8, and first, second, and third de-multiplexers 6, 5 and 7 are switched by a switching control signal, and switching of the usage of an FD controller circuit 1 or that of an RD controller 2 can be performed, and it is connectable to both the RAM disk device and the floppy disk device, and is capable of controlling then. Also, by using the same physical interface on the storage device side as that of a conventional device, a conventional floppy disk device can be connected as it is. Furthermore, by using the same physical and logical interface on a host system side as that of the conventional system, a floppy disk controller can be replaced by a conventional floppy disk controller as it is, thereby, the control can be performed without necessitating the change of the software of the host system.
