A data storage device with optical interface comprises a data storage medium, an optical transmission means, and a power unit. The data storage medium is a magnetic or a semiconductor medium. The optical transmission means is a bi-directional infrared ray transceiver. The power unit provides necessary power for the said device to work. The said device, when wirelessly connecting to a handheld client system capable optical transmission, reads writes, and deletes data on the said storage medium according to the operations requested by the client system. Thus, by replacing storage medium the said device can expmd the handheld system to almost infinity. This advantage is most beneficial when a PC system is not near by.
