There is described a read/write device which enables realization of miniaturization, a reduction in weight, improvement in the accuracy of step feed, and reliability. The read/write device includes heads, a carriage, a stepper motor for moving the carriage stepwise, and a medium drive motor for spinning a recording medium. The stepper motor further includes a rotor, a first stator which is formed from multilayer magnetic material and is fixedly positioned so as to surround the rotor, a second stator formed in substantially the same way as the first stator, and a holder for housing the first and second stators.
