Abstract: PURPOSE:To increase a reception rate and to improve the interchangeability of cards by decoding data by a variable length or fixed length system for a loaded medium and verifying data only by the fixed length system for a medium written in by the primary device. CONSTITUTION:When a card position detecting part 23 detects the insertion of a magnetic medium and a measuring part 15 for interval of magnetic flux inversion measures the inverted interval, a conversion system setting part 14 sets a read-out system to be a variable length conversion system and decodes the data. When the data are failed to be read by the variable length conversion system, the read out system is changed to a fixed length conversion system and again executes decoding. When writing in by means of the primary device is finished, the read out system is set to be the fixed length conversion system and reading operation is executed. In such a constitution, a large jitter is allowed for the loaded magnetic medium so as to improve the reception rate and the allowance of the jitter is reduced for the magnetic medium written in by the primary device so as to hold the interchangeability of the magnetic medium wide.
