Hi, Gentleman. I do not know if here is the correct place to ask these questions. But, alas, this is vinil (I guess), it has grooves, it was mastered and pressed and play music. Using a conventional stylus/cartridge. But, it is a endless loop tape. I never found information about how a Tefifon tape mas nanufactured. Any Troll here does have the answer? Must be very interesting. Thanks a lot. Claudio.
