Description

I

The invention relates to accumulators of information in which the recording and reading of information are based on the relative movement of the recording medium and the converter, and can be used in the equipment for magnetic recording of digital information arriving asynchronously with the recording.

There are known devices for recording information that contain a magnetic recording unit and a buffer accumulator 1. The disadvantage of this device is high hardware costs.

Of the known devices, the closest technical solution to the invention is a device for recording information, comprising a serially connected first code converter, a drive and a second code converter, a control unit, the first and second outputs of which are connected respectively to the input of the second code converter and one of the accumulator inputs. h 2.

The disadvantage of this device is the high cost of equipment associated with a significant storage capacity and causing a decrease in reliability of the device.

The aim of the invention is to increase the reliability of the device.

This is achieved in that the device contains an address code comparison circuit and a switch whose input is connected to the third output of the control unit and an output to the first input of the address comparison circuit whose second input is connected to the output of the first code converter, and the output to another input of the accumulator .

The drawing shows a structural scheme of the device for recording information. The device comprises a first code converter 1, a drive 2, a second code converter 3, which serves to interface the device with a tape drive mechanism 4, a control unit 5, a switch 6 and an address code comparison circuit 7. The first, second and third outputs of control unit 5 are connected respectively to one of the two inputs of accumulator 2, inputs of converter 3 and switch 6. The first input of comparison circuit 7 is connected to the output of switch b, the second to the output of converter 1, and the output to another input drive 2.

The device operates as follows. The input information in the form of a serial code is fed to the input of converter 1, in which it is converted into a pulse parallel code. The numerical part of the code from converter 1 is written to the drive 2. The read information from drive 2 is fed through converter 3 to a tape drive mechanism 4 for recording on a magnetic tape. The information reading of the accumulator 2 is carried out using the control unit 5. The converter 3 coordinates the information from the accumulator 2 with the input parameters of the tape mechanism 4. The control unit 5 synchronizes the operation of the converter 3 and also generates pulses fed to the switch 6, which switches the required values of the address codes, which are then sent to the first the input of the circuit 7 comparison of address codes. The second input of the address code comparison circuit 7 receives the address part of the input information code from converter 1. If the address code values from the converter 1 coincide with switch 6, the address code comparison circuit 7 produces a signal enabling the writing of the numeric part of the input information code to the drive 2. The control unit 5 operates in such a way that the reading of information from the storage unit 2 occurs

before switching switch 6 to the next value of the address code.

The proposed device is simpler known, has less weight and dimensions due to a decrease in storage capacity, which is determined only by the digit size of the code.
