Edison Diamond Recordable Disc 10 Blanks - "Voicewriter"
This sale is for 10 of the discs pictured .. breaking it up to sell it quicker.
The Voicewriter was a dictation format introduced by Thomas A. Edison Industries in the late 1940s. Unlike Edison’s previous cylinder-based dictation machines, this used an almost 7-inch diameter flexible red resin-based disc, labelled as an ‘Edison Diamond Disc’ (not to be confused with the earlier Edison Disc Record / Diamond Disc of 1912 to 1929).
Like the SoundScriber and Audiograph systems, sound was embossed in grooves onto the discs, but unlike these competing disc formats, Voicewriter discs can be played back on a phonograph turntable with a microgroove stylus and a US-style adaptor for 7-inch singles (although the speed is slightly-less than 33⅓ rpm)*. (**Information is from the Museum of Obsolete Media).
