Soundscriber machine from 1944 advertisement
SoundScriber was a dictation machine introduced in 1945 by The SoundScriber Corp. (New Haven).[1] It recorded sound with a groove embossed into soft vinyl discs with a stylus.[2][1][3] Similar competing recording technologies were the Gray Audograph and Dictaphone DictaBelt. The machine could record 15 minutes of dictation on each side of a thin (.01 inch)[3] flexible 6 inch vinyl disk turning at a rate of 33 RPM, at a density of 200 grooves per inch.[1] The disks cost about 10 cents each.[1][3] The machine had two tone arms; a recording arm driven by a worm gear that created the groove with a diamond stylus, and a pickup arm with a sapphire stylus for playback.[3][1] A foot operated playback/pause and reversing switch was used for transcribing.[1]

Unlike some other recording technologies of the time, the recording stylus created the groove not by cutting the vinyl but by embossing (plastically deforming) the surface, leaving no waste plastic chips to get into the mechanical works.[3][1]

The format remained popular for two decades before it was superseded by magnetic tape recorders, due in part to the robustness of the discs and the ease with which they could be mailed. The green discs with their characteristic square center hole came in two sizes, 6 inches (known as "Mail Chute") that played for fifteen minutes, and 4-inch "Memo Discs" with eight minutes of recording time. The soft vinyl medium limited the number of times a disk could be played back without degradation of the audio quality.
