Abstract

197,378. Deane, L. D. Feb. 7, 1922. Disc records.-In order that an independentlyplayed musical instrument may be tuned with a gramophone record when the latter is reproduced, a long note of given pitch is recorded on the disc, in a groove D running around or outside the record proper C. The tuning note is sounded before the musical reproduction occurs, which is effected as usual by movement of the stylus from the periphery towards the centre of the record. The groove D may be circular, or may, as shown, be a spiral connected by a smooth groove E to the main record groove C. Specification 18760/04 is referred to.
