Description
(54) СПОСОБ МАГНИТНОЙ ЗАПИСИ И ВОСПРОИЗВЕДЕНИЯ ЦИФРОВОЙ,ИНФОРМАЦИИ(54) METHOD OF MAGNETIC RECORDING AND REPRODUCTION OF DIGITAL INFORMATION
1one
Изобретение относитс к области магнитной записи, а именно к способам магнитной записи и воспроизведени цифровой информации .The invention relates to the field of magnetic recording, in particular to methods of magnetic recording and reproducing digital information.
По основному авт. св. № 594523 известен способ магнитной записи и воспроизведени цифровой информации, основанный на формировании одноканальной последовательности разнесенных во времени сигналов, записи символов через выбранные интервалы времени, образованные двум соседними сигналами , распознавании их значимости путем измерени длительности интервалов времени между соответствующими сигналами при их воспроизведении. При известном способе также запись каждого последующего символа любого вида производ т в интервале времени , равном разности последующего интервала и значени записываемого символа, если эта разность меньще длительности исходного интервала. Кроме того, по известному способу распознавание значимости символа в процессе воспроизведени информации осуществл ют путем измерени абсолютно-й величины разности двух соседних интервалов вре.мени. Этот способ позвол ет обеспечить высокую достоверность воспроизведени записа1П ой цифровой информации, однако не позвол ет обеспечить достаточно высокую плотность записиИ.According to the main author. St. No. 594523 discloses a method of magnetic recording and reproducing digital information, based on the formation of a single-channel sequence of separated signals, recording symbols at selected time intervals formed by two adjacent signals, recognizing their significance by measuring the duration of the time intervals between the corresponding signals when they are played. With the known method, each subsequent symbol of any kind is also recorded in a time interval equal to the difference of the next interval and the value of the recorded symbol, if this difference is less than the duration of the original interval. In addition, according to a known method, the recognition of the significance of a symbol in the process of reproducing information is carried out by measuring the absolute value of the difference between two adjacent time intervals. This method allows to ensure high reliability of reproduction of recorded digital information, however, it does not allow for a sufficiently high recording density.
Цель изобретени -- повыщение плотности загп1С 1 без увеличени погрешности результата воспроизведени цифровой инфор мации.The purpose of the invention is to increase the density of Cip1s 1 without increasing the error in the result of reproducing digital information.
Это достигаетс за счет того, что в процессе воспроизведени при распознавании знач1 мости символа одновременно с изме1)е нием абсолютной величины разности двух соседних интервалов времени производ т он ределеиие иол рйости каждого воспроизвод 1 юго импульса.This is achieved due to the fact that in the process of reproduction, when recognizing the significance of a symbol simultaneously with a change in the absolute value of the difference between two adjacent time intervals, it produces a value for each reproduction of 1 south pulse.
ДАагнитна запись и воспроизведениг цифровой информации по предложенномх способу происходит следующим образом.The digital recording and playback of digital information on the proposed method is as follows.
