ABSTRACT:
A data storage apparatus excelling in portability by enabling data to be transferred between a detachable first recording medium having a relatively small capacity and an undetachable second recording medium having a large capacity. In particular, as a memory card using no special card is employed as first recording medium, and there is no need to specially provide a head elevating mechanism or a medium loading mechanism for the second recording medium, the size and thickness of the apparatus can be reduced.
