<P>PROBLEM TO BE SOLVED: To provide a large capacity storage medium provided with a storage card conversion interface. <P>SOLUTION: A power supply 16 is connected to a circuit board 30, and supplies power to a built-in or an exterior mass storage medium 10. A storage medium 12 is connected to the circuit board 30 by a transmission interface 22. A virtual card conversion connection interface is provided with the appearance size of a standard small-sized storage card on one end, is directly inserted to a second insertion vessel (slot) and is connected to the circuit board by an interface signal connection line on the opposite end. By the operation interface of a digital electronic device, the standard command and control program of the small-sized storage card are controlled through the virtual card conversion connection interface, they are converted to the command and control program of the storage medium and data are preserved, backed up and recorded in the storage medium. <P>COPYRIGHT: (C)2004,JPO |
