I don't know of any such disk packs (in fact, there is one combination,
I forget which, which will result in a volume spindle swedged into the
drive spindle -- making the drive so much worthless hardware)
However, TK50 and TK70 fit the bill... you can read TK50s on a TK70,
but not write them. Tapes written on a TK70 cannot be read on a TK50.
