Acetates are records that is more or less often recorded at 78-rpm speed, and are general, 10 inches in diameter, and they are recorded on primal home made disc recorders, which had been on widespread sale during the 1940s. Acetate records are of aluminium metal base coated with black lacquer and the recording stylus scores the groove whilst recording.
