Thank you all! This was a new one for me, but clearly not a new one in the business.

I do worry about storing them B-wound long term for tapes for which we are not the custodians, precisely because of Adrian's point. But leaving them B-wound for a few pre-transfer days may be a good option.

Thanks again,

Marcos

Dear Marcos,

I have employed "B" winds for improved tape pack for more than twenty-five years. Its benefits are noted especially with analog tapes. The process seems to re-stress the plastic to counter the effects of poor packs due to fast winds before storage, as well as warped packs. Usually, it is important to identify the problem early and use a B when storing the tape for later use. The more time the better, but improvement has been achieved after as little as sixty days. Furthermore, I have found that if the tape is returned to storage with a B wind, there is no need to change the reversal as long as the container is correctly marked.
