Abstract

325,199. Bryson, H. C. Nov. 6, 1928. Disc records. - The opposite sides of doublesided disc records are differently formed or finished so that they can be distinguished in a bad light. Order of playing in association with a kinematograph is thus facilitated. Opposite sides may have a different colour, generally or inset, which is visible in a poor light. Alternatively, projections may be provided on one side and, if desired, a recess on the other, such markings being on the non-recorded part. Specification 315,104 is referred to.
