IPC: G06K7/00
Filed: 2003-02-28
Abstract: <P>PROBLEM TO BE SOLVED: To detect illegal data undetectable by horizontal and vertical parity check in a medium reader for reading data on FM recorded medium.  <P>SOLUTION: A time internal of a recording signal from a detector (11) for detecting an FM-recorded signal of a medium (9) is calculated and is compared with a reference interval to judge data. A possibility of illegal data is judged by the time interval and the judgement result, and the medium is read again when data having the possibility of illegal data is detected in two or more positions. Thus, the error of data having illegal data undetectable by horizontal and vertical parity check, in two positions can be detected, and a possibility of erroneous read is reduced to improve the read performance. Since retry is performed only when there is a possibility of illegal data, an influence upon the read processing time and the transaction time is lessened.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
