Record carrier to use a method of converting the coded bit stream the user bit stream, a method for detecting a synchronization pattern in the signal, a synchronization pattern can be inserted freely, signal, reproducing apparatus and recording apparatus

摘要

The present invention proposes a synchronization pattern for RLL code with certain constraints. Instead of including a synchronization pattern, by the code word at the end of the section constraints channel all of the code prior to the synchronization pattern along with the p leading bit, and the second section following a synchronizing pattern along with the q trailing bits of the synchronization pattern to pattern As adapted by the code word of the one, the pattern is selected synchronization pattern is to have a tray q ring bit and p leading bit. This synchronization pattern inserted freely to be inserted after encoding, it is removed before decoding can be obtained, and coder decoder efficient is obtained consequently.
