Method and apparatus for communication and storage of binary information
Abstract
Abstract METHOD AND APPARATUS FOR COMMUNICATION AND STORATE OF BINARY INFORMATION ON A MEDIUM HAVING TWO SEPARATELY IDENTIFIABLE WAVEFORMS OR STATES AND HAVING A PLURALITY OF NEARLY UNIFORM BIT CELLS. BINARY "ONES" ARE TRANSMITTED IN SELECTED BIT CELLS BY WRITING A TRANSITION BETWEEN THE TWO STATES AT THE CENTER OF EACH SUCH BIT CELL. BINARY "ZEROES" ARE TRANSMITTED IN ALL OTHER BIT CELLS BY WRITING A TRANSITION BETWEEN THE TWO STATES AT THE LEADING EDGE OF ONLY THOSE OF THE "ZERO" BIT CELLS NOT IMMEDIATELY FOLLOWING A BIT CELL HAVING A TRANSITION THEREIN. SEPARATION OF DATA IS ACCOMPLISHED BY VIEWING EACH BIT CELL AND SEPARATING ANY TRANSITION DETECTED AT THE CENTER OF A BIT CELL AS A "ONE" AND CONSIDERING ANY OTHER BIT CELL AS A "ZERO."
