Abstract: <P>PROBLEM TO BE SOLVED: To adopt a method, for additionally recording data to a reflecting film of a recorded disk, also for an error correction coding area.  <P>SOLUTION: Two symbol parity data (Figure 11B) are produced from four symbol (Figure 11A) data. Six symbol data are subjected to EFM (eight to fourteen modulation) to convert 8-bits of each symbol into 14-bit bit pattern data. The 8-bit data pattern of each symbol is converted into a 14-bit bit pattern (Figure 11C). Two symbols in a pit/land stream (Figure 11D) formed on the disk are rewritten. The one is originated from the symbol data (0x40). Additional recording to the pit/land stream lengthens the pit length (Figure 11E). A reproduction side converts reproduced 14-bit data into 8-bit data. This results in rewriting of the original data (0x40) into (0x22). The parity is revised so that the additionally recorded data symbol (0x22) is not detected as an error.  <P>COPYRIGHT: (C)2004,JPO
