PROBLEM TO BE SOLVED: To enable a user to easily recognize data contents preserved in a storage medium at sight, to reduce the cost of the storage medium, or to improve the preservability of the storage medium. SOLUTION: A printer 2 and a scanner 3 are connected to a computer device 1. An image file F0, to be preserved as digital data in the computer device 1, is converted into print pattern data by a data conversion program 100, after being divided by every 4 bits and is printed as a print pattern on a print form P by the printer 2. The scanner 3 reads the print pattern printed on the print form P and transmits it to the computer device 1 as printing pattern data, and a data-restoring means 200 restores it into an image file F1. |
