This meshes with my recollection of how it went as well.  The "Digital"
part of "Digital Linear Tape" was from Digital Electronics Corp (DEC).
They made the original drives, then later sold/licensed/whatever
the technology to Quantum, who made it 'better' and rebranded DEC's
TKfoo/CompacTape as DLT.
