Abstract

PURPOSE: To improve flexibility of cards, by dividing data into several positions or recording repeatedly the same data in several positions and by handling respective data parts independently and by making it possible to untilize information even if an arbitrary partial data part is destructed.
CONSTITUTION: One-track components of data are recorded on card 2, and the data part is divided or the same data is recorded repeatedly in several positions. For example, data parts D(A), D(B) and D(C) are individual data obtained by dividing the data part into three in contents; and even if error is generated in data part D(A), card 2 is regraded as effective when data parts D(B) and D(C) are read correctly, and read of information of data parts D(A), D(B), and D(C) is completed.
