Abstract :
Design of a new Run Length Limited (RLL) code is presented. The new coding scheme has coding rate of R=2/5, with the minimum runlength between two successive transitions equal to 4. This RLL (4, ∞) code uses channel capacity extremely efficiently, 98.7% and consequently it achieves density rate of DR=2.0. It has better efficiency than many other currently used codes for high density optical recording, or transmission.
