We have invented devices to record what we can see, and devices to record what we can hear.
Why haven’t we invented something to record what we can smell?
How would this work if we did?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

Recording implies identifying every single chemical on a scent profile. And chemical identification is difficult and highly impractical on an individual scale. Also, every scent is not composed of the same chemicals, so “playback” for every “recording” would also be difficult and impractical.
