Description
(54) УСТРОЙСТВО ДЛЯ МАГНИТНОЙ ЗАПИСИ -И КОНТРОЛЬНОГО ВОСПРОИЗВЕДЕНИЯ ЦИФРОВОЙ(54) DEVICE FOR MAGNETIC RECORDING - AND CONTROL REPRODUCTION DIGITAL
1one
Изобретение относитс к приборостроению и может быть использовано в технике цифровой магнитной записи.The invention relates to instrumentation and can be used in the technique of digital magnetic recording.
Известны устройства дл магнитной записи и контрольного воспроизведени цифровой информации, содержащие блок записи , блок воспроизведени и две магнитные головки, одна из которых служит дл записи цифровой информации, а друга - дл контрольного воспроизведени 1.Devices for magnetic recording and control reproduction of digital information are known, comprising a recording unit, a reproducing unit and two magnetic heads, one of which is used for recording digital information and the other for control reproduction 1.
Однако при их использовании пробел на магнитном носителе между зонами информации должен быть увеличен на рассто ние между рабочими зазорами записывающей и воспроизвод щей головок, что снижает эффективность использовани магнитного носител .However, when using them, the space on the magnetic carrier between the information zones should be increased by the distance between the working gaps of the recording and reproducing heads, which reduces the efficiency of using the magnetic carrier.
Наиболее близким по технической сущности вл етс устройство дл магнитной записи и контрольного воспроизведени цифровой информации, содержащее блок записи , блок воспроизведени и универсальную магнитную головку. Оно позвол ет производить запись и контрольное воспроизведение цифровой информации за один проход магнитного носител относительно универсальной магнитной головки, т.е. исключитьThe closest in technical essence is a device for magnetic recording and control reproduction of digital information, comprising a recording unit, a reproducing unit and a universal magnetic head. It allows recording and control reproduction of digital information in a single pass of a magnetic carrier relative to a universal magnetic head, i.e. to exclude
ИНФОРМАЦИИINFORMATION
перемотку магнитного носител к началу зонь1 и последующее контрольное воспроизведение информации и повысить, таким образом , скорость записи в 3 раза путем уменьщени временной задержки контрол . Это 5 достигаетс благодар введению блока формировани стробирующих импульсов, вход которого соединен с входом блока записи, а выход со стрОб-выходом блока воспроизведени 2.rewinding the magnetic carrier to the beginning of zone 1 and the subsequent control reproduction of information and thus increase the recording speed by 3 times by reducing the time delay of the control. This 5 is achieved by introducing a gating pulse shaping unit, the input of which is connected to the input of the recording unit and the output to the strobe output of the playback unit 2.
10 Однако при использовании устройства усложн етс конструкци универсальной магнитной головки за счет повыщени требовани к ее быстродействию, что обусловлено мешающим действием сигналов электродвижущей силы самоиндукции универсальной Магниткой головки.; . , ,, „, ,10 However, when using the device, the design of a universal magnetic head is complicated due to an increase in the speed requirement, which is caused by the interfering action of the electromotive force signals of the self-induced Magnetic head .; . , ,, „,,
Цель изобретени - повыщение скорости записи и упрощение конструкции универсальной магнитной головки.The purpose of the invention is to increase the recording speed and simplify the design of the universal magnetic head.
