The device has three operating modes: erase mode, write and read mode.

In the erase mode, the erase inputs 28 and erase markers from the external control device simultaneously feed a control pulse, through which the drivers of 5 current pulses and the additional driver 11 of current pulses produce a signal whose polarity is opposite to the polarity of the current recording pulses, and the amplitude is that during the passage of this impulse through the write-sti-tires. run 4 and the additional write-erase bus 10, the magnetic field caused by it leads to an irreversible change in the magnetization along the entire length information carriers 3 and 9 and uniformly reversal them, for example, in the state - Bf.

the swarm of the element 30i I input. At the same time, the zero potential from a single trigger output 32 | arrives at the second input of element 302 I. After that, the first clock pulse from the input of 19 clock pulses goes through element 30i and to the first output 23 of the control unit 1 and further to the start of the mechanical voltage pulse generator 2, and also to the trigger installation input 32i, which enters a single state, opens the second input element 302 And and closes the element 30i I. The pulse from the output of the element 30i And also goes to the first inputs of the elements 304 and 30, And the output does not pass, because the elements 304, 30 and go go closed zero the potential from the input 21 of the read mode of the control unit 1. The second and subsequent clock pulses come through the open element 302 And to the counting input of the counter 33 and to the first input of the element F3 I, which is open at the second input by the potential from the input 22 of the recording mode. From the output of the element 30.3, the clock pulses go to the third output 25 of the control unit 1, and then to the control inputs of the current drivers 5i - 5 „. The words on the information inputs 14 of the device are synchronized with the clock pulses, therefore, the control signals from the control unit and the information signals from the inputs 14 of the device arrive at the inputs of the current drivers 5i-5p of the current pulses simultaneously. In accordance with the codes of the words, current pulses are generated in the write-erase buses. The amplitude of these pulses is such that in the absence of a mechanical voltage pulse, they do not lead to an irreversible change in the magnetization of the 3i-Sn media, but, in the presence of a mechanical voltage pulse in the local area of the information carrier, interact with it, producing an irreversible change in the local magnetization of the information carrier, translating it, for example, into the state - | -Bj ,. The mechanical voltage pulses are distributed in all 3i-3 information carriers in parallel, therefore all word bits are recorded, each on its own information carrier, at an equal distance from its beginning. The counter 33 of the control unit 1 counts the incoming clock pulses and after the arrival of the t- | -1 clock pulse, where w is the number of words recorded in the memory, sends a signal to the first input of the OR element 311, which then goes to the zero input of the counter 33 and trigger reset input 32 |. Thus, the control unit 1 returns to its initial state after recording the entire volume of the memory.

In read mode, the counter 33 is reset and the trigger 32 | -32c is reset, similar to the write mode. Then on. the input 21 of the read mode receives a positive potential, and the input 22 of the write mode

zero potential is applied. At the same time, a signal to erase markers is applied to the erase input of device markers 29. The erasure of markers is performed in the same way as erasing the storage medium 3. The first clock pulse through the opened element 30: And enters the input of the trigger setup 32 | and to the first inputs of elements 304 and 30A, And, to the third inputs of which positive potentials are fed from the input 21 of the mode, correspond to the masked discharges for which no comparison is made. Permanent potentials are supplied to the first inputs of elements 39 of EQUALITY from the corresponding outputs of the register of the feature and to their second inputs with a frequency of clock pulses from the outputs of the read amplifiers the corresponding bits of the words read from the memory. With the coincidence of the signals at the output of the elements 39 EQUAL. Element 30i And open at the second 1 VALUE, the logic input signals a positive potential from the zero output of the trigger 32i, and the element 302 is closed with a zero potential from the single output of the trigger 32i. The first clock pulse also enters the input of the former 2 mechanical stress pulses, as in the recording mode, and excites mechanical stress pulses in all 3i-3p information carriers. The first clock pulse goes through the unit and goes through the elements 40 OR of the word selection unit 13 to the corresponding inputs of the element 38 I. If the bit is masked, then the second input of the corresponding element 40 OR has a high potential and regardless of the comparison result to the corresponding input of the element 38 And a logical unit arrives. At the last input of the element 38, there is a positive potential from the fourth output of the OST I, the delay element 34 and the element 26 of the control unit 1. When a match OR to the fifth input 27 of the control unit 1, and then to start an additional driver 8 impulses of mechanical voltage. From the output of element 30i, the first clock pulse arrives at the unit of all the bits in the match blocks, except masked ones, the output of the word selector 13 is a signal that goes to the input of the additional current driver 11, and into the bus

The trigger input 32i, which closes the write-eraser 10, is signaled, which

the element 30i And opens element 302 I. From the output of element 30.5 And the first clock pulse converts the trigger 322 into a single state, as a result of which the element 30 $ opens on the second input and closes element 304 I. At the same time, the trigger 32z is in the zero state, the element ZOe I is open at the first input with a positive potential from the flip-flop 32z, and at the second input with a positive potential from the input 21 of the read mode. From its output 26, a positive potential arrives at the control input of the word selector unit 13. The zero potential from the output 24 of the control unit 1 closes all elements 1 - 7 "And at the third input. In carrier x in30

when interacting with a mechanical voltage impulse, in the additional information carrier 9, it records the selected word marker. Recording is performed in the same way as in information carrier 3 in recording mode. The delay of the delay element 34 is chosen such that it is equal to the delay of the signal in the reading amplifier, the word selector unit and the additional current pulse driver. In the result, in the additional information storage medium 9, markers of the selected words are recorded at the same positions as the words themselves in the storage media 3.

After passing the clock pulse, counter 33 outputs a signal, zeroing formations 3i-3,1 in parallel spreading through element 311 OR counter 33

and trigger 321. The next clock pulse produces the same switch as the first clock pulse, except that it passes through the element 30 And, and not through the element 304 And, enters the 5th input of the installation of the trigger 32z, translates it into one state the At the output 24 of the control unit 1, a positive potential appears, opening the elements 7i-7 "I" at the third input. Element ZOe AND block 1

Mechanical voltage pulses that induce the inputs of amplifiers 6i-6, t emf corresponding to the codes of the recorded words that come from the outputs of the amplifiers to the information inputs 16 of the word selection unit 13 and the second inputs of the AND elements with the clock frequency. In additional information carriers 9, a mechanical voltage pulse is propagated with a delay relative to the mechanical voltage pulses in the control is closed at the first input

information carrier 3i-3l. The delay is constant and equal to the delay in the delay element 34 of the control unit 1. The second and subsequent clock pulses through the element 302 and arrive at the counting input of the counter 33.

In the register of the sign 35 before the start of the reading mode, the key word is entered, and in the register 36 of the mask of the block 13 of the choice of words - the mask code, and the units in the mask code

the zero potential from the zero output of the flip-flop 32z and the word selector block is closed at the control input by the zero potential from the fourth output 26 of the control unit 1. From the output of the ZOA element, such a 55-second pulse without delay is supplied through the 3b element OR to the output 27 of the control unit 1. As a result, at the outputs 23 and 27 of the control unit 1, the signals appear at the same time and arrive at the start of the formation correspond to the masked bits for which no comparison is made. Permanent potentials are supplied to the first inputs of elements 39 of EQUALITY from the corresponding outputs of the register of the feature, and to their second inputs with a frequency of clock pulses from the outputs of the read amplifiers the corresponding bits of the words read from the memory are received. When the signals at the output of the 39 EQUALITY elements coincide, signals of a logical unit appear and pass through the elements 40 OR of the word selector 13 to the corresponding inputs of the 38I element. If the bit is masked, there is a high potential at the second input of the corresponding OR 40 element and regardless of the result of the comparison to the corresponding input of the element 38 And a logical unit is supplied. At the last input of the element 38 is the positive potential from the fourth output and 26 of the control unit 1. When all the bits in the matching blocks, except masked ones, coincide, the output of the word selector 13 appears, which is fed to the input of the additional current driver 11, and into the bus

write-erase 10 signal is given which

when interacting with a mechanical voltage impulse, in the additional information carrier 9, it records the selected word marker. Recording is performed in the same way as in information carrier 3 in recording mode. The delay of the delay element 34 is chosen such that it is equal to the delay of the signal in the reading amplifier, the word selector unit and the additional current pulse driver. As a result, in the additional information storage medium 9, markers of the selected words are recorded in the same positions as the words themselves in the storage media 3.

After the clock pulse has passed, the counter 33 outputs a signal which zeroes through the element 311 OR the counter 33

element 311 or through counter 33

and trigger 321. The next clock pulse produces the same switch as the first clock pulse, except that it passes through the element 30 And, and not through the element 304 And, is fed to the input of the trigger setup 32h, translates it into one state . At the output 24 of the control unit 1, a positive potential appears, opening the elements 7i-7 "I" at the third input. Element ZOe AND block 1

From the output of the ZOA element, such a 55-second pulse without delay is supplied through the 3b element OR to the output 27 of the control unit 1. As a result, at the outputs 23 and 27 of the control unit 1, the signals appear simultaneously and arrive at the start of the mechanical voltage pulse shapers 2 and 8. The mechanical voltage pulses simultaneously propagate through the carriers 3 and 9 of information. The signals corresponding to the bits of the selected words and the markers of these words simultaneously, through the reading amplifiers 6 and 12, arrive at the inputs of the AND elements and at their outputs successively in time appear the words chosen from the memory. After the input of the counter 33 2in + 2-ro clock pulse, a signal appears at its output, which through element 311 OR resets the trigger 32 and zeroes the counter 33. The device is thus prepared for the next cycle of operation.
