One tape system I've seen that doesn't have a shoeshine problem is
Ampex's DCRsi.  It can write at any speed between 0 and 30 MB/sec.  It
uses 1" tape with a tranvserse scanning head.  It looks like it is
mostly used for instrument recording (like aircraft black boxes).

The T10000 is particularly difficult because it only has 2 streaming
speeds.  50MB/sec and 120MB/sec.
