Reduction Of Modulation Noise In Analog Full Track Recording Using Multitrack Replay Techniques
Modulation noise is a well known phenomenon in magnetic recording systems using analog signal representation. Modulation noise has been defined as a "noise which exists only in presence of a signal". In addition the modulation noise is a function of the instantaneous amplitude of the recorded signal. Based on statistical methods, a noise reduction should be possible. The paper describes a test equipment, the test procedure and the results. The test system is based on a full track recorded tape. The playback process uses multiple track playback and gives the ability to correlate the different output signals. The output signal of each track will be digitized and processed. Based on this procedure, it can be shown that a noise reduction is possible.
