Re: [ARSCLIST] NY Times: Researchers Play Tune Recorded before Edison

What Emile Berliner perfected...to be exact...was the lateral-cut flat
disc record/player...! Edison had apparently experimented with both,
but being a perfectionist, figured out that the fidelity of a flat
record would vary slightly between first and last turn of the spiral...
while a cylinder record would play at the same rate from first to last
turn (especially if the reproducer was driven across the cylinder by
a feedscrew...!). The difference was that flat disc records could be
stamped out in quantity, while cylinders were not moulded until early
in the 20th century...!

Bell and Tainter also experimented with discs, although I don't recall whether or not they did anything with lateral modulation. But their patent application, like that of Edison, illustrates disc machines - including one that apparently records by cutting the underside of the disc!
