The Development of Disc Cutting Heads.
Proper restoration of historic disc recordings is assisted by an accurate knowledge of the characteristics of the equipment used in the recording process. This paper traces the evolution of electro-mechanical disc cutting heads from the early 1920's to the last models. Use is made of the electro-mechanical equivalent circuits to analyse the performance of moving iron, moving coil and motional feedback types.
