Abstract
An input string of binary data bits which is a random sequence of 0s and 1s is selectively spaced encoded into an output string of binary channel bits which is a sequence of 0s and 1s. An input string of binary data bits are recursively encoded according to run-length selection means having rate p/q where p is the number of input data bits that are encoded into q-channel bits. The channel bits obey constraints such that the encoding specifies an ordered n element list of integers that are the lengths of the selected runs of consecutive zeros, denoted b.sub.0 -1, b.sub.1 -1, . . . , b.sub.n-1 -1, and such that the element list of integers does not contain all the integers between the minimum element, b.sub.0, and the maximum element, b.sub.n-1.
