摘要：a digital circuit to generate a signal to control so as to increase the degree oflinear polarization of a signal has alternating current recording.the polarization signal isdigital control (24) is mixed (48) with an analog signal of known frequency and constantlevel, and tape (41).the circuit detects a level of polarization and on the relevantregistration has a shell (54) of the reproduction signals.each has a peak (56), comparedwith a known level of hyperpolarization (58).the circuit compensates for the bias level (20)detects a record over the distance between the recording and reproducing head (41).(42)to obtain an optimum recording bias level. the level of polarization is stored (18) detectsand unchanged during the power interruption.
