  Hans,

  I don't know what causes the "rubber" to turn gooy but I know it's common
for the drive wheels in ALL of the HP tapes and mag card drives to turn
gooy with age. I took a HP 7912 tape drive apart last week and the "rubber"
had liquified and actually dripped into the other parts of the tape drive
sort of like paint. The HP-85 belts are made of a different material, they
don't turn gooy but just fall apart with age.

  My $.02 worth,

  Joe
