Abstract
PURPOSE:To prevent a read error and to elevate a reliability, by recording the magnetic information by the same contents extending over two blocks, storing them at every read information, and checking to collate whether they conform with each other or not. CONSTITUTION:Magnetic information is recorded by the same contents extending over two blocks, in a magnetic card of a currency transcation device, etc., a read signal from a head 3 is supplied to an analog processing part 4, and a data signal (a) which has decided ''1'', ''0'', and a synchronizing signal (b) are outputted. And, they are supplied to a bit counting part 5, a ''0'' bit counting part 7 and a character constitution part 8, a control part 6 is operated, a character signal (e) is stored in the first and second storage parts 9, 10, simultaneously collating check of each information is executed, and when one cannot be read, the other is made effective. Accordingly, a read error, etc. can be prevented exactly, and a reliability of read information is greatly elevated.
