Abstract
Data having a basic data length of m bits is modulated to a variable-length code having a basic code length of n bits. A sync signal is added to the data after a minimum bit-run in the data. The sync signal exhibits two or more patterns, each pattern breaking a maximum bit-run and having six channel bits for identifying each sync signal. The two or more patterns are distinguished from one another, with a detection distance of at least two therebetween.
