PURPOSE:To obtain a flexible system constitution which is set for the encoding method at each time by setting encoding data in a memory card file driver on an OS. CONSTITUTION:A register 22 where conversion data of encoding is held and a gate 21 which inverts the polarity of an address line for the purpose of encoding are provided to constitute hardware 2. Software 3 is provided with the memory card file driver which can sets encoding data on the file managing function on the operation system (OS), and hardware 2 and software 3 are combined to constitute an encoding system. Consequently, encoding data is set in the file on the OS to freely change and set mapping for encoding of data. Thus, the flexible data encoding system for memory card is obtained. |
