I think the only way to remedy this is to carefully go through the reel and edit off the leader. 

I take it you can play the programme.

Subject: Re: [ARSCLIST] Tape Shed-Sticking & stripping

Hi all, We also have a few Ampex 406 1/4" 10.5" stereo tapes professionally recorded and stored in London around 77-80 that are suffering binder adhesion to leader tape. I'd be interested in hearing comments and suggestions as to handling this problem. Obviously the tapes require baking yet the main problem is the oxide sticking to the leader tape edited in between tracks. There are a few types of leader tape and have found that coloured and printed leader tape is the most problematic. We have very gently hand wound tapes whilst dousing the problem areas with isopropyl prior to any baking, but the oxide still sticks to the leader. We have also tried baking as well as dehydrating to no benefit. Does anyone have experience of this problem with Ampex 406? Will soaking in silica gel in the fridge be of benefit? So far there hasn't been any splicing-tape adhesive bleed which is another problem we're having with EMI Tape. Over the weekend I will attempt to post a link to photos of the tapes for everyone.

There is a CHANCE that month-long cold soak in a desiccated atmosphere (silica gel inside double freezer (or foil) Zip-Loc bags in the fridge (not freezer)). It has worked for some 3M 176 that showed this symptom. It has also not worked for other tapes. Jim Wheeler gave me this technique. I don't know his source. I haven't used it much. The other thing to try is VERY slow unwinding - 1.88 in/s or slower. Sometimes that alone helps. The tape in the photo was baked based on a consensus of the people at the seminar (including the tape owner) because we didn't have time for cold soak and we wanted to see what would work (or not). Since that article, I have had good results with 3M201 which had the same problem and the 1.88 in/s wind-through solved it. Good luck!
