Изобретение относитс к технике магнитной записи, а именно к устройствам частотно-модулированной записи.This invention relates to a magnetic recording technique, namely, frequency modulated recording devices.

Известно устройство дл записи информации , содержащее коммутатор, преобразователь аналог-код, частотный модул тор и блок записи 1J.A device for recording information comprising a switch, an analog-code converter, a frequency modulator, and a 1J recording unit are known.

Однако это устройство позвол ет записать сигнал только одного канала.However, this device allows recording of only one channel signal.

Наиболее близким по технической сущности к изобретению вл етс устройство, содержащее блок управлени , блок ввода информации, соединенные с ними коммутатор и генератор тактовых сигналов и блок записи 2.The closest in technical essence to the invention is a device comprising a control unit, an information input unit, a switch connected thereto and a clock generator and a recording unit 2.

Целью изобретени вл етс увеличение числа регистрируемых каналов и сокращение времени регистрации.The aim of the invention is to increase the number of channels registered and reduce the time of registration.

Это достигаетс тем, что предлагаемое устройство снабжено частотным модул тором и блоком формировани , один выход которого подключен к блоку записи, другой выход - к блоку управлени , а вход - к выходу частотного модул тора, вход которого соединен с выходом коммутатора.This is achieved by the fact that the proposed device is equipped with a frequency modulator and a shaping unit, one output of which is connected to the recording unit, another output to the control unit, and the input to the output of the frequency modulator, the input of which is connected to the switch output.

На фиг. 1 изображена блок-схема описываемого устройства; на фиг. 2 - временные диаграммы, по сн ющие его работу.FIG. 1 shows a block diagram of the described device; in fig. 2 - time diagrams that show his work.

Устройство содержит блок 1 управлени , блок 2 ввода информации, коммутатор 3 и генератор 4 тактовых сигналов, соединенные с блоками 1 и 2, и блок 5 записи.The device comprises a control unit 1, an information input unit 2, a switch 3 and a 4 clock signal generator connected to blocks 1 and 2, and a recording unit 5.

Устройство снабжено частотным модул тором 6 и блоком 7 формировани . Один выход блока 7 подключен к блоку 5 записи. а другой выход - к блоку 1 управлени . Вход блока 7 формировани подключен к выходу частотного модул тора 6, вход которого соединен с выходом коммутатора 3.The device is equipped with a frequency modulator 6 and a forming unit 7. One output of block 7 is connected to block 5 of the record. and the other exit is to control block 1. The input of the forming unit 7 is connected to the output of the frequency modulator 6, the input of which is connected to the output of the switch 3.

Устройство работает следующим образом .The device works as follows.

Claims

The signals of the generator 4 and channels 8 through the input unit 2 are connected in series by the switch 3 to the input of the frequency modulator 6. The switch 3 also connects the source 9 of the reference voltage to the input of the frequency modulator 6. The signal at the input of the frequency modulator 6 is shown in FIG. 2a, and the signal at the output of the same modulator — in FIG. 2 b. The signal of the modulator 6 is divided by frequency by the formation unit 7 and the divided signal (Fig. 2, 0) is supplied to the recording unit 5. In block 7, signals are formed which, together with the signals of generator 4, are used in block 1 of control to synchronize the operation of switch 3. Recording the recorded information by a single magnetization differential reduces the registration time and allows an increase in the number of channels recorded. Apparatus for recording information comprising a control unit, an information input unit, a switch connected to them and a clock signal generator and a recording unit, characterized in that, in order to increase the number of channels registered and shorten the registration time, it is equipped with a frequency modulator and a block the formation, one output of which is connected to the recording unit, the other output - to the control unit, and the input - to the output of the frequency modulator, the input of which is connected to the output of the switch.
