Abstract
A storage device includes: a read/write mechanism which is actuated in accordance with a selected one of two or more sets of control data so that a read/write operation is carried out to read data from or write data onto a recording medium; a detection unit for detecting a source voltage from a host system, and for detecting whether one of source voltages from the host system has been switched to another source voltage; a control unit for controlling the read/write operation of the read/write mechanism in accordance with the detected source voltage; and a reset unit for resetting the control unit to an initial condition when the switching from the one of the source voltages to the another source voltage is detected as being in process, so that the controlling of the read/write mechanism is withheld until the end of the switching.
