Home recording

One example of an "instantaneous recording" machine, available to the home
recording enthusiast by about 1929 or 1930, was the "*Sentinel
Chromatron"*machine.

The
Sentinel Chromatron recorded on a single side of uncoated
aluminum<http://en.wikipedia.org/wiki/Aluminum>;
its records were read with a fibre <http://en.wikipedia.org/wiki/Fibre> needle.
It was "rather unstable technology" which produced poor sound quality in
comparison to shellac records and was rarely used after
1935.[<http://en.wikipedia.org/wiki/Production_of_gramophone_records#cite_note-histdet-0>
