Abstract
This paper describes a new recording code format, Eight to Fourteen Modulation (EFM), designed for digital audio discs with optical readout. Attention is focused primarily on trade offs between conflicting parameters such as information density and d.c. content that led to the choice of the adopted format EFM.Keywords
