PURPOSE:To prevent occurrences of mistakes in error correction, by adding an error correcting code after fixed length is secured by adding dummy code to data corresponding to the final end of divided variable length data. CONSTITUTION:Picture information in a page buffer 2 is condensedly processed at every line, and, when the picture information at the end of a line is read out, an end-of-line signal EOL is detected by an EOL detecting circuit 25 and a signal ''1'' is outputted from the circuit 25. Therefore, a read signal from the buffer 2 is obstructed by an inverter circuit 27 and an AND circuit 23, and, at the same time, a dummy code generating circuit 31 is started to operate by the output of another AND circuit 30 and a dummy code signal F is supplied to an optical disk device 10 through OR circuits 26 and 21. In this way, the length of picture information at the end of line can be adjusted to a fixed length by adding the dummy code. |
