We describe a (d, k) = (1, 8) runlength-limited (RLL) rate 8 / 12 code
with fixed codeword length 12. The code is block-decodable; a codewor
d can be decoded without knowledge of preceding or succeeding codeword
s. The code belongs to the class of bounded delay block-decodable (BDB
) codes with one symbol (8 bits) look-ahead. Due to its format, this c
ode is particularly attractive for use in combination with error-corre
cting codes such as Reed-Solomon codes over the finite field GF(2(8)).
