Abstract

Improvements in systems to produce an information record, characterized in that said systems comprise a light source; means for periodically modulating the light from said source; means for shaping said light into a relatively narrow elongated beam; a Y shutter modulator arranged in the path of said beam; an audio signal source coupled to said modulator to activate it in response to said audio signals, whereby said beam is modulated, and optical means for directing said doubly modulated light beam towards said recording medium to expose said medium to said modulated light, by which when developing, said recording means will include said information record.
