发明名称 Method and system of magnetic recording and reproducing with ultra-high density
摘要 Method and system of perpendicular magnetic recording and reproducing with ultra-high density for use in computer storage, audio, video recording euipment. Marks, as logical "1"-s are recorded at predeteremined distance from one another and their magnetic axes oriented in the opposite directions, as logical "0"-s are non-magnetized, forming pattern similar to chess-board order with the zero potential lines, eliminating crosstalk. Interaction "head-medium" is based on non-contact magnetic modulation, eliminating tribology problems. System may compose single or multi track medium, transporting linearly or rotating, with the immovable, quasi-immovable or scanning bi-polar or uni-polar magnetic heads, which have extremely small pointing conjugation area for interation with superminiature dimensions of magnetic fields of marks. System is realized by forming and recognizing the logical meaning of signals under checking of the strict general sequence different-directed alternation marks inside the tracks and in the neighboring tracks relatively of each other.
