Four simple runlength constrained codes for digital optical or magnetic recording are presented. Parameters are R = 1/3, (d, k) = (1, 2), R =1/4, (d, k) = (4, 8), R = 1/4, (d, k) = (4, 7) and R = 1/4, (d, k) = (5, 9). Both the finite-state transition diagrams for the encoders and sliding-block decoders are presented.
