DLT tapes and streamer
Another standard with long history. The characteristical thing
is that cartridges have only one reel - the other one is fixed
in streamer. After the cartridge is loaded in, the tape is
pulled from it through its way to another reel. To remove tape
it's needed to re-wind it back to cartridge.
First units from 1984 allowed to store 100MB of data. Newest tapes can hold up to 800GB. Of course they're not backwards-compatible. See here for details.

These devices had electromagnetically locked handle which allowed tape to be loaded in.
