I was thinking more in terms of space. A disk is much more efficient in
this regard. You can stack N times the number of disks in the same space
that a drum takes up.
The problem with disk, of course, is the variable BPI.
Today, with the electronics so cheap, the CD-ROM is made
with a spiral track and it runs at a constant BPI by
changing the rotation speed as it reads the disk.
