Error Recovery by Character Recognition

      Disclosed is a system for paper memory as WORM for storing
binary data (program, applet, etc.).

      Generally, decoding the stored binary data must be done without
error because binary data would be useless if any bit were changed
during its decoding.  Moreover, in case binary data is stored on
paper by printing in some way, it may occur that the quality of
printing is lowered by copying with a copier or by sending it with
fax; however, it  must be decoded without error.

      To solve the issue, this system encodes binary data with
characters and prints the encoded characters on paper.  When it is
time to decode, the characters are recognized by a commercial
character recognition program, and binary data is decoded.  Any
encoding method is  allowed if the encoded characters can be
recognized by a recognition program.  With this method, quality
deterioration is permitted as long as  a recognition program
functions well.  Then, it is possible to copy the  paper that stores
binary data, send it via a fax, or fold and carry it.
