operation, the device unloads the head(s) to the ramp position as soon as possible
when received the IDLE IMMEDIATE command with the Unload Feature. When
the writing operation is stopped, the device keeps the unwritten data. And, the
device keeps the unloaded state until receiving a Soft / Hard Reset, or a new
command except IDLE IMMEDIATE command with the Unload Feature.
