<p>A code data recording method of recording magnetically code data on a magnetic card (1) having a magnetic layer for reading and writing data magnetically. A plurality of belt-like bar marks (2a, 2b) whose widths are different from each other, are arranged to form a code. One or more code having the same data are magnetically recorded repeatedly. Thereby, even when a part of the bar marks cannot be read, that is, the code data cannot be read because of the contamination or damage of the magnetic card (1), from the remained parts of the bar marks, the whole of the code data can be reproduced.</p> |
