Abstract
PURPOSE:To shorten a processing time by storing data from a host computer in write units alternately in 1st and 2nd buffer memories provided to a reader writer, and writing the contents of one memory on the memory of a memory card while storing data in the other memory. CONSTITUTION:The reader writer 2 is equipped with the 1st and 2nd buffer memories 4 and 5 with capacitor which is larger the write unit of the memory of the memory card 3 and smaller than the total capacity, and when data from the host computer 1 are written on the memory card 3, data of a 1st write unit is stored in the buffer memory 4. When data of a next write unit is stored in the buffer memory 5, the storage contents of the buffer memory 4 are written on the memory card 3 simultaneously. When data of a write unit following said unit is stored in the buffer memory 4, the storage contents of the buffer memory 5 are written on the memory card 3. Consequently, the data from the host computer 1 are written on the memory card 3 in real time and the processing time is shortened.
