Method of recording information on a medium in the form of electrical signals

A method consisting in that a portion of the working layer is acted upon at first by a uniform thermal field and simultaneously or successively by a uniform vector field whose vector lines are perpendicular to the carried surface. At least one of the fields is obtained by converting the electrical s...

Beschreibung
Zusammenfassung:	A method consisting in that a portion of the working layer is acted upon at first by a uniform thermal field and simultaneously or successively by a uniform vector field whose vector lines are perpendicular to the carried surface. At least one of the fields is obtained by converting the electrical signals transmitting the information being recorded. When recording on a carrier portion heated to a temperature higher that the softening temperature of the working layer binder (3), particles (4) are aligned along the vector lines whereby optical density of said area within the medium is changed according to the recorded information. The time is started to be fixed at the moment the vector field is no longer applied.
