Abstract

618,349. Sound records. KOLB, O. K., and PETERSON, A. C. G. Oct. 23, 1946, No. 31533. Drawings to Specification. [Class 40 (ii)] In a sound record having an invisible trace, such as a magnetic tape or a film opaque to ultra-violet light and transparent to white light as described in Specification 350,965, a visual signal indication record is added to facilitate editing. The additional trace may be recorded simultaneously with the invisible sound record, or may be added at a later stage by re-recording from the original sound trace, and may be made by a recording stylus or by an inking device as described in Specification 423,505. The signal indication record need only cover a limited frequency range and the recording device may be operated by a rectified current to produce a trace which follows the envelope of the sound waves. The indication record may also be on a separate carrier.
