Age of masters


Seeing new releases using re-masters which to me means they use the original 40+ year old master and twiddle some knobs.

Do 40+ year old masters still have viable iron oxide?  Would high frequencies suffer? Or do I misunderstand re-mastering?

Watch this discussion, those masters are timeless and if they are stored properly in the archives then no problem to use them even 50 years later.
