Tape damage from end clips

I was going through a lot of 70+ reels of audio tape. Most of them had plastic end clips on them. The clips were used to keep the end of the tape from unraveling.

We had the same thing with film. Although the film clips were thin metal and the film is a lot tougher than audio tape.

Roughly 30% of the tape with end clips had damage to the tape. Below is an example of one of the more extreme cases.

I noticed if the tape was wound properly with few ridges there was no visible damage to the naked eye with the tape end clips.

Generally speaking the rough wound tape is from rewinding or fast forward. When a tape is played from head to tail at normal speed it usually winds flat. And with film we have the same issues of trying to get a flat wind in our reels especially when we are using manual rewinds as the speed and tension varies and can produce an uneven wind.

They did make a spring metal keeper for 8mm film that did not have the problems of the other styles of keepers. It was similar to a film keeper made out of heavy cardboard that was held around the film with a rubber band. The metal keeper would work on magnetic tape, but it would have to be made out of non-magnetic stainless steel or other non-magnetic material.
