Dolby noise-reduction system - Wiki
"Dolby noise reduction is a form of dynamic pre-emphasis employed during recording, plus a form of dynamic de-emphasis used during playback, that work in tandem to improve the signal-to-noise ratio. The signal-to-noise ratio is simply how large the music signal is compared to the low level of tape noise with no signal." Chalk up another gem from geoff that adds to his extraordinary cred.

Improve the s/n and destroy the s. Just great. Me loves some cassettes.
