Abstract

The invention relates to the field of magnetic recording, to devices for processing information reproduced from a magnetic recording medium. The purpose of the invention is to increase the speed of the device. The measurement information reproduced by playback unit 1 enters the information processing line 4 via the key block 3 and the analog-digital converter 4. The control signals are fed to the switch 5, where the operating mode is selected. The current parameter value (RTD) in the parameter change mode from playback unit 1 through selector 7 and code converter 8 is supplied to zone selection unit 9, in which a control signal is generated, passing through switch 5 and OR element 11 to filtering unit 10, ensuring delay for a specified time interval. At the same time, the HRC enters the comparison unit 13, generating a signal for the duration of the interference, it passes through the AND 12 element and is stored in the OR 11 element with the switch signal 5. The result of the addition is delayed by the filtering unit 10 at the end of the section for a predetermined time interval from the end of the interference. 1 il.

Description

The invention relates to magnetic recording, in particular to devices for processing information reproduced from a magnetic recording medium,

The aim of the invention is to increase the speed of the information processing apparatus.

The drawing shows one of the possible variants of the proposed device for information processing.

The device contains a playback unit T from a magnetic recording medium, connected to the information processing line 2 via serially connected key block 3 and analog-to-digital converter 4, and to switch 5 through block 6 threshold elements. The playback unit 1 is also connected with a selector 7 connected in series, a device 8 with a register executed, and a zone selection unit 9, the outputs of which are connected to the switch 5.

The device also contains a filtering unit 10, the output of which is connected to the key block 3, the element OR 11, the element 12 and the comparison unit 13. One of the inputs of the filtering unit 10

is connected via the OR 11 element with the filtering output 30 at the end of the section at the set point of the switch 5. The other input of the filtering unit 10 is connected to the register output of the 8 code converter. Element And 12 is connected by the input to the output of block 10 of the filter. The input of the comparator unit 13 is connected to the code converter 8, and the output is connected to the second input of the AND 12 element connected by the output to the input of the OR 11 element.

The device works as follows.

The measurement information reproduced from the magnetic recording medium by the playback unit 1 is fed to the information processing line 2 via the key block 3 and the analog-adipher converter 4 in certain sections. The formation of control signals for the input of these sections is an irrah time interval since the end of the interference.
