Abstract
The storage device of the invention has a ramp mechanism which shakes out the head onto the disk medium, and causes the head to evacuate from the medium to hold it. The command queuing processing unit stores input/output commands into the command queue in the order of issuance by the host, and then, executes the commands in arrangement in the increasing order of the medium access time. Completion of commands is responded to the host in the order of completion of execution. The end of command is responded to the host in the order of end of execution. The emergency evacuation processing unit interrupts, upon receipt of an emergency evacuation command from the host during operation of the command queuing processing unit, operation of the command queuing processing unit and protects the head by causing the head to evacuate from the medium to the ramp mechanism.
