Abstract
A controller of a recording device issues a secure command to a storage device, and then waits the time estimated necessary for the storage device to execute the secure command before issuing the next secure command. When a controller of the storage device is executing the previous command, it notifies the recording device of being in process. When the previous command has been completed normally, the controller moves to the next process. Information for estimating the execution time of the command is obtained from the storage device in advance.
