A 1,2 run-length-limited (RLL) code having rate 2/5 is described. The error propagation of the code is limited to less than 5 errors in the decoded data from any one error in the encoded data string. In encoding, let the current state of the encoder be represented by bits z0, z1 and z3 . The encoder receives input bits x0 and x1 .
