‘Recording Sound - Old and New’

From analogue to digital - from a hair-thin wire to a flash drive!

Wire recorders recorded and played on a spool of hair-thin wire. The precursor of today's magnetic tape cassette recorder, they had the enormous advantage over gramophone records of being able to be wiped and re-recorded. My father, a college lecturer at the time, used this spool to record seminars in the late 1940s!

While the wire spool could record perhaps 30 minutes, today's digital thumb drive can record for hundreds of hours at near-perfect quality!
