Weren't those the tapes that randomly cut off in the middle of recording? I remember hea

Yes, Ferro-chrome. http://tapetardis.wordpress.com/tag/type-iii/

I tried updating my status from my phone and it decided not to post all of it. Type III was designed to overcome the limitations of typical types I&II tape by combining both kinds of particles. Advancements in type II (formulations better than CrO2) and the introduction of type IV killed it off.
