PURPOSE:To reduce the access time of a system by starting an access to the next target sector with reference to the address order which is stored immediately after the data is read out of or written to a certain sector. CONSTITUTION:A command sent from a host CPU1 is sent to a buffer CPU22 through an interface 21 for CPU1. The CPU22 executes an access to the command under the control of a control memory 23, and then immediately whether the same sector receives or not so far an access is checked from the storage contents of a buffer 25. If a previous access is decided, the command is assumed as a target sector with reference to the address data stored next and before supply of the next command. Thus an access is started. This can reduce the overall access time. |
