<p><P>PROBLEM TO BE SOLVED: To easily and securely make pointer control over encoded data and further to easily recover even if a reproduction error occurs. <P>SOLUTION: An arbitrary fixed-bit pattern is added as head decision information 12 right before each encoded data and then when a pointer detected with an encoded data length 11 is different from the head of next encoded data, the head decision information 12 is not detected to detect the pointer being incorrect. In this case, next head decision information 12 is detected from the pointer of the last encoded data to determine the pointer of the next encoded data, so the pointer control over encoded data is easily and securely made, and even if a reproduction error occurs, a recovery is easily made. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
