When I started using the IBM 360 mainframe at the University of
New Mexico, they still had a 7 track tape drive which was around
for reading obsolete tapes.

Just curious...does anyone still have a working 7 track drive?
What were the advantages/disadvantages of 7 track as opposed to
9 track?

BTW, the 9 track drive had low, medium, and high densities in those
days: 200 BPI, 556 BPI, and 800 BPI.  1600 and 6250 hadn't even
been thought of...
