Abstract
Magnetic recording circuitry supplies to the recording head in addition to the signal to be recorded a train of constant amplitude pulses of extremely short duration and of low duty cycle; for example, pedestal pulses of polarity corresponding to the signal are superimposed on the signal for higher positive and negative signal amplitudes, while alternating polarity pulses are supplied during periods of low signal amplitude, such that the transducer system exhibits a substantially linear transfer function.
