<p>The circuit provides statistical marking of magnetic recording and reading tracks using a pulse generator, a logic unit and a delay element. The outputs of one of the pulse generators are connected to counters and to the input of the other generator. This second generator has one output connected to a shaper and its other output connected to the control input of the electronic gate. The output remains connected to the counting input of the following pulse counter. The output of the shaper is connected to the recording amplifier, and via a delay line to one of the inputs of the logic unit. The output of the reading amplifier is connected to the signal input of the electronic gate. The output of this is connected to the recording preparation circuit.</p> |
