Re: [ARSCLIST] Damaged Tapes

Hi, Peter
I understand this is not uncommon in the film world where the emulsion
coating adheres to the next layer.  I believe a thin teflon wedge
applied tangentially to the start-point of the bond is used to gently
tease the layers apart.  

If you try to just pull the adhesion apart, by hand or with a deck, the
force is in a direction which increases the bad separation forces....
radial rather than tangential... and the tape is severely flexed at the
start-point.

Good luck
Nigel

Subject: [ARSCLIST] Damaged Tapes

Hi


I have just received 2 reels of 1/4inch tape recorded in 1968.
To the best of my knowledge this is the first time they have been played
since then.
They have been stored Tail Out
All the titles have been leadered with plain white plastic leader The
Tape has never been baked When I spooled the first reel back to the
start, to play, I found that on 3 of the titles the oxide had adhered to
the leader, having been stripped off the tape backing. Thus rendering
the first 3 or 4 seconds unuseable.

This is obviously unrecoverable

When I came to the second side, I spooled up to the leader and the moved
the tape slowly by hand, the oxide is still sticking to the leader.
I have no idea what make the tape is, as it is not Emitape, but in an
EmiTape box Has anyone met this, and how did you attempt to deal with it
Any help would be appreciated

Thanks
