Description

3

The device contains input stitches of digital information format 1, connected through the first switch 2, connected to the input command bus for record 3 and to Bx6 | i command bus for playback 4, s

block buffer memory 5, connected to the output of the first circuit AND 6. Circuit AND 6 is connected to the output of the pulse driver, 7 directly and through an additional AND 8 connected to the input command bus for recording 3, counter 9, decoder 1O and

trigger 11. Scheme I 8, counter 9, decipher g | rator 10, trigger 11 and the first circuit U 6 1 are part of the shaper frame zash | - «s .; .,,,

The buffer memory block 5 is connected to the input bus line of the query query 12 af to the second switch 13 connected to the output digital bus, 14, and to the input command and playback bus 3 and 4 buses. Secondary,. the swarm switch 13 is connected via the write current drivers 15 with recording magnetic heads 16 connected with magnetic tape 17, Tape 17 is also connected with magnetic modulation magnetic heads 18 connected to the playback amplifier unit 19 connected to the first switch 2, ,

Block B is connected through the pulse shaper of the memory 2O to the first inputs of the flip-flops 21 and 22 entering; the composition of the stepper signal generator; the movement of the magnetic tape. The latter also includes a clock pulse generator 23, And 24 and 25 Circuits, a phase comparator 26 and a power amplifier 27. The second input of the Tpiirrepa 21 is connected to block 19, and the output with an And 24 circuit connected to the input command bus for playback .four. The second input of the trigger 22 is connected to the decoder U, and the output with the AND 25 circuit connected to the input ;, the comald bus for writing 3. The output of the clock pulse generator 23 is connected to the AND 24 and 25 circuits whose outputs are soy (Dineni with phase comparator 26, connected to the power amplifier 27, the power amplifier connected to the stepper electric motor 28, on the shaft of which the angular position sensor 29 is fixed, connects to the driver 7. The electric motor 28 is mounted so that it can be screwed into the magnetic movement (Penta 17.

In the process of recording, upon receipt of the times of the potential, on the input bus, the | coder for recording 3 digital information is cher. the first switch | 2 enters the block

(Buffer memory 5. When the sh block is fe, the shaper 20 rotates the shaft of an electromotor 28 at a certain angle. As a result, from the output of the pulse shaper 7, an additional circuit li 8 passes a signal that provides digital information from block 5, which | ) through the second switch 13 nocrynaetf and the write current driver 15,

The device reduces the reproduction error in digital data recorders and can be used to record digital information by zones of a certain length.
