RECORDING DEVICE AND REPRODUCING DEVICE

摘要

PURPOSE:To reduce the effect of an error without increasing additional information such as error correction by including a specific SYNC pattern to a code word or a final part of linked code words and detecting the SYNC pattern when code synchronization is unlocked at reproduction. CONSTITUTION:A signal inputted from an input section 4 in a coder is inputted to a pattern selector 7. The pattern selector 7 selects an information pattern inputted from an information pattern input section 5 and an end pattern inputted from an end pattern input section 6 according to an input signal and links them and outputs the result to an output section 8. A variable length decoding section 15 in a reproduction device stops decoding when an error information input section 13 detects an error and inputted to the section 15 and restarts a variable length decoding according to a head position of a code word inputted from a SYNC pattern detection section 14. Thus, even when an error takes place at the reproduction, the code synchronization of the variable length code is simply restored.
