Abstract
A binary data encoding and recovery technique for which the encoding is carried out by separating the binary data into successive data words each containing an equivalent number of data bits, generating one or more code signals representative of each data word where each code signal corresponds to a signal change at one of a plurality of signal change positions in a data cell associated with the data word and is spaced from adjacent signal changes in the data cell by at least a prescribed minimum amount, and assuring that succeeding signal changes occurring in a sequence of data cells are spaced at least the prescribed minimum amount by determining whether a signal change in one data cell would be spaced less than the prescribed minimum amount from a signal change in an adjacent data cell and in such event providing for the code signals related to such signal changes to be merged into a code signal corresponding to a signal change positioned at the boundary of the adjacent data cells so that the prescribed minimum spacing is maintained between all signal changes. In certain instances, additional signal changes are inserted at strategic locations to limit the distance between successive signal changes.
