I have used DDS tapes almost exclusively in my DAT players. I have had problems with the transports wearing out using the 90 meter tapes. The heads still look good though. The decks that I have had trouble with 90m tapes are a Sony 59es and a Tascam DA-P1. Some of the beefier studio decks probably would fair better.
Cheers,
Jim
