Invertibly mapping binary sequences into rate 2/3 (1,K) run-length-limited coded sequences with maximum transition density constrains

Invertibly mapping binary sequences into rate 2/3 (1,K) run-length-limited coded sequences with maximum transition density constrains

A method and means for reducing high-duty-cycle unconstrained binary signal sequences in storage and communications processes and systems by invertibly mapping such sequences into a (1, k) rate RLL codestream constrained to a duty cycle substantially approximating one-third. That is, binary sequence...

Zusammenfassung:A method and means for reducing high-duty-cycle unconstrained binary signal sequences in storage and communications processes and systems by invertibly mapping such sequences into a (1, k) rate RLL codestream constrained to a duty cycle substantially approximating one-third. That is, binary sequences ordinarily mapping into high-duty-cycle RLL-code sequences are either inhibited from repeating indefinitely or excluded.
