Recording with Feedback-Controlled Effective Bias

Authors: Jensen, Jørgen S.

Journal of the Audio Engineering Society · Volume 31 · Issue 10 · pp. 729–736 · October 1983

Abstract

In magnetic recording, high frequencies present in the signal act as bias for lower frequencies. If supersonic bias is dynamically reduced by the same amount as the added effective bias of the audio signal, several advantages result. The theoretical aspects of constant effective bias, the implementation in a cassette recorder, and the resulting improvements in quality are described.
