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.
