FIELD: magnetic recording. ^ SUBSTANCE: device for controlling quality of magnetic carriers contains, connected serially: multi-track block for magnetic recording-reproduction, reproduction amplification block and threshold elements block, and also registration device. Outputs of threshold element block are combined by adder, output of adder is connected to input of registration device, while block of threshold elements is made with setting input, which is connected to setting bus of device. ^ EFFECT: possible control over quality of magnetic layers of carriers with high resolution and high productiveness without recording of test signals on them. ^ 1 dwg |
