Description

one

This invention relates to the field of computing.

The device includes devices for recording information on a magnetic tape, containing a tape mechanism with a stepper motor connected to a control unit, and a reading head, the outputs of which are connected through series-connected transducer-code converters and amplifiers to magnetic heads.

The speed of tracking the contour of such devices is constant and taken by the one that is necessary, that the error of tracking the curvilinear part was minimal. When recording information on a magnetic tape from a drawing or from a product whose contour is described both by straight lines and by small curvature radii , the performance of such devices is quite small, so KBii for tracking with minimal oiiiiidfiuii for the straight part

The contour speed of tracking is much higher than the speed of collision behind the curvilinear part of the contour with the same tracking error.

5 The aim of the invention is to improve the performance of a device for recording information on a magnetic tape.

The goal is achieved by the fact that the device contains arithmetic analog blocks, code-analog converters and analog-code converters, the inputs of which are connected to the outputs of arithmetic analog

15 blocks connected via code-analogue converters to the outputs of amplifiers, and the output of the adder through a series-connected arithmetic analog block and

20 an analog-code converter is connected to the input of the control unit. Thus, an increase in the productivity of the device is achieved by reducing the time for recording information on a magnetic tape.

from a product having a complex curvilinear contour, by tracking it at different speeds without reducing accuracy.

The drawing shows the block diagram of the proposed device for recording information on a magnetic tape.

The device contains a table I with a read head, displacement-code converters 2.3, amplifiers 4, 5, magnetic heads 6, 7, tape drive mechanism 8j, code-analog converters 9, 10, arithmetic analog blocks

P, 12 and 1, adder 13, converter analog-code 15, control unit 16, stepper motor 17,

The reading head table is, in the particular case, a coordinate system with a read head installed instead of a writing tool.

The outputs of the read head for each coordinate are connected through a serially connected displacement transducer 2 or 3 and an amplifier or 5 connected to the magnetic head 6 and 7 of the tape drive mechanism 8 and to the inputs of the transducer code analog 9 or 10.

The outputs of the latter through the arithmetic analog blocks II or. | 2 are connected to the inputs of the adder 13. The output of the adder is connected through a series-connected arithmetic analog unit 14 —and the analog-code converter 15 is connected to the input of the control unit -16 of the stepper motor 7..

The device works as follows. .

When the reading head moves along the contour at the outputs of amplifier 4 or 5, a pulse appears that goes to the magnetic head b or 7, as well as to the inputs of the code-analog converter 9 or 10, where they are converted to analog values. The signals from the code-analogue converters 9 and 10 are fed to the inputs of analog arithmetic

And 12 blocks, on the outputs of which appear analog signals with modules equal to -squares of modules of input signals. These signals

5 are summed in adder 14, and the non.j chesh signal is fed to the input of the arithmetic analog block 13, the output of which is equal to the square root of the input signal module. The output signal of block 13 is converted into a pulse train using an analog-to-1 converter) 15. Pulses with the converter analog-code 15,

15 arriving at the input of the control unit 16, commute in the winding of the stepping motor, which is defined by traces of gel, 17.
