ABSTRACT:
The invention proposes an apparatus for encoding an information signal. The information signal can be a (d,k) sequence. The apparatus encodes the (d,k) sequence into a (d+n,k+n) sequence by changing the number of zeroes between each time two subsequent ones in the sequence by n. The information signal can also be a RLL sequence of the type (d,k). The apparatus encodes the signal into a RLL sequence of the type (d+n,k+n) by changing the runlengths by n bitcells each.
