The tape system was really interesting to me during the short time that it was there (upgraded shortly after I started); I didn't expect to be able to find any useful information on it but surprisingly, an old IBM Promo video exists on YouTube. If you're interested in seeing what it looks like, I put it at 1:04, since that's where the 3D rendered exterior view starts. They can be extended and ours was much longer than that one in the video if memory serves (one end to the other of a complete DC floor diagonally; it forced a really odd layout for the original mainframe, cabinets, and then ultimately the tape library that replaced it).
