ABSTRACT:
A prerecorded track on a disc is automatically tracked resulting in a radial tracking signal. Components of this signal are stored during a prerecording interval. During recording these stored components are used to produce a restored radial tracking signal which is used to radially position the recording energy source and keep the newly recorded tracks at a fixed distance from the previously recorded tracks.
