[Problem] As to a memory card drive for operating multiple memory cards in parallel and executing high speed reading and writing, the amount of current supplied to the memory card drive varies among apparatuses connected and supplying electric power to the memory card drive due to their different capabilities, and therefore apparatuses applicable to the memory card drive are limitd. [Means for Solving the Problem] In a recording device having one or more semiconductor memories mounted thereon, the number of semiconductor memories operating in parallel is restricted according to the available supply current of an accessing apparatus to which the recording device is attached.
