Abstract: This invention relates to a storage device including a wireless unit which performs wireless communication with another device, a storage unit for storing data, a processor which transmits, based on a command from the device that has been received by communication through the wireless unit, data stored in the storage unit from the wireless unit to another device and stores data received by the wireless unit in the storage unit, and a battery which supplies power to the wireless unit, storage unit, and processor.

Abstract: A portable data storage device has a wireless data communications function. A CPU of the device writes data transmitted by a radio wave from a communications object device to a data storage medium. At the time of writing, the CPU generates transfer control information including a range of the transmitted data and identification information of the communications object device. When a wave reception state of the device has become poor, the CPU stops the writing to the data storage medium. When communications connection has been resumed, the CPU performs control to continue the writing from a point where the writing was stopped, on the basis of the transfer control information.
