The phonograph was both in a cylinder and a disc form.
For example: all of the following are "phonorecords" under the law: A wire recording; a 16-rpm, 33-rpm, 45-rpm or 78-rpm phonograph record (vinyl disc), a reel-to-reel tape, an 8-track tape, a compact cassette tape, a compact disc, an audio DVD, and an MP3 file stored on a computer, compact disc or USB flash drive.

This picture inspired him to initiate the first Computer Art Contest in 1963. The annual contest was a key point in the development of computer art up to the year 1973 ...
As far back as 1916, in the article “Upcoming Science of Music and the New Era in the History of Music”, Arseny Avraamov proclaimed his view on the future of the Art of Music: “By knowing the way to record the most complex sound textures by means of a phonograph, after analysis of the curve structure of the sound groove, directing the ...
