Hi guys

Does anyone know anything about PDM cassette tapes?

I have a PDM ME and ME-X metal formulation tapes.

PDM = Philips-DuPont Magnetics. The joint venture to sell Philips-made tape in the USA. They are pretty good. Their products are same as Philips brand in Europe.

Philips and DuPont had a joint venture in the 80s to make CDs for the record companies called PDO.

Thanks
That makes sense.

It's strange that the Nakamichi engineer didn't rate them!

I'll try them again to see how they perform.
