DCC tape is BASF Video Chrome Tape.
It is not regular Chrome Tape, but tape with a special coating that prevents any shedding.
The shedding residue, unfortunately normal with basically any tape, was damaging the heads so badly in the early development days (source Daniel Staudacher and Gijs Wirtz at Tandy and Philips in various interviews documented by the DCC Museum), that heads would only last a few hours. Originally they used regular Chrome Tape.
They made 2 adjustments. The thin film head received a coating and they switched from regular Chrome Tape to the BASF Video Chrome tape.
When using only DCC pre recorded and recordable you can clearly see this effect. There is nearly no residue transferred to the head. Some residue could be on the felt pad, but that is coming from the back of the Video Chrome Tape and a result of specially created DCC Back Matting and cutting the BASF Video Chrome tape to smaller size.
That is also the reason why there are 2 side felt pads in a DCC shell.
The abrasive and corrosive affect of regular analog tape still happening on the coated new thin film head was documented in 1993 and 1994 . Now that most heads are 30 years old it is even better to not be using any analog tape on DCC players.
