It's hard to say; under CT, I think they've
always been "cassettes", of the "self-erasing" variety. (Being tech from the 70's [cf. the Sony Walkman], I presume they're
Mission: Impossible inspired: "This tape will self-destruct in 5 seconds. Good luck, Jim." only without the messy smoke puff...)
In the modern vernacular, I'd expect them to be more like USB thumb drives: something that's plugged in to provide data and has a driver on it that wipes it clean after the transfer.
I figure the "one-use" "self-erasing" "cassettes" are actually fairly common as an anti-hijacking and risk-management technique. Corsair-attractive ships, particualrly subsidized merchants, might not have the Generate program installed (and Anti-Hijack would be configured to disallow software installation in flight), and would instead rely upon an
authenticated Jump plot to be externally loaded. (The authentication, again probably via Anti-Hijack, prevents hijackers from smuggling their own "cassette" aboard.) It's much harder to commandeer a starship whose Navigate program won't work with just any old data.
Furthermore, with all the above discussion about navigators and plotting accuracy, I can see the case for a big company like Naasirka subcontracting to provide "quality-assured" pre-calculated Jump plots to large corporate users. This underwriting might then in turn reduce insurance premiums for ships using "guaranteed" calculations. (Insert sabotaging-this-process-for-excitement-and-profit adventure hook here.)
What then of the required navigators? Probably a combination of back-up safety (in addition to basic sanity-checking of the pre-generated plot, maybe the Generate program is installed but is encrypted and requires a key for emergency use, and the Navigate program of course routinely logs where it got its Jump plot from for later forensic purposes) and strong unions.
Plus, the "naivgator", being a command position with few practical duties, is a good candidate for being a megacorporation's on-board minder...
