<p>PROBLEM TO BE SOLVED: To easily record and reproduce music data into/from a memory stick (memory card) with a conventional mini disk recording/reproducing device. SOLUTION: The cartridge 21 of an adapter 20 on which a memory stick 10 is loaded is set to be the same form as the cartridge of a mini disk. A connection coil 31 and a thermosensitive element 32 are arranged in an opening 24 and they are made to face a magnetic head 42 at the time of loading them on a recording/reproducing device. They are electromagnetically connected with the coil of a magnetic head. The coil and the optical beam of the optical head 43 are magneto-optically connected. In the adapter, the connection coil and the memory stick are connected through a transmission/reception circuit and CPU, music data is written into the memory stick in accordance with the amount of the energy of the optical beam, which corresponds to a recording/ reproducing mode and is detected by the thermosensitive element, or the music data is read from the memory stick.</p> |
