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?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

We can and we did. There were scent printer that can “download” scent from supported webpages and create it for the users as early as the 90s. It just didn’t sell well enough to be continued. I’m not sure if it can conveniently record any scent your want or not
