ABSTRACT:
The invention relates to the generation of a digital magnetic recording signal modulated in phase in correspondence with the transitions of the corresponding data signal. According to the invention, the D.C. component of the recording signal is suppressed so that the recording winding can be excited by this signal by means of a transformer. The recording head can include only a single turn.
