Re: Different tape colours

I think there was a lot more ferric (brown tape) in the 70's and 80's. Even some looked almost grey.


From something I found on the web:


Quote:
reddish-brown and/or light-brown = basic ferric tapes

chocolate-brown or dark-brown = enhanced (cobalt doped) ferric tapes and pseudo-chromes (cobalt doped again)

dark blueish-black = true chrome tapes
