Re: [ARSCLIST] Cassette obsolescence - Loss of Lubricant/Sticky S hed

[Geeta Jatania <geeta.jatania@xxxxxxxxxx>]

Thanks Richard and others for your comments.  

I have read other material and spoken to colleagues at other institutions
which and who express similar thoughts to yours Richard.  Capturing to 96/24
from cassette does seem a little redundant.

As standard practice we always carry out azimuth adjustment before capture.
Storage space isn't such a huge issue for us with this particular project as
each item only contains one music track up to 5 minutes in duration.
Capture at 96/24 was being trialled as this is a relatively small
collection.  Our general standard capture for tape is either 44.1/16 or
48/16.

I've recently been seconded back to audio.  Amongst doing other things I am
reviewing some of our current practices so it's always helpful to hear
different people's opinions in this type of forum.

As for LOL, we are looking at ways to address this issue.  I have read some
of the discussions on the list.  Yes Marie is an expert in the area - Marie
and I both previously worked together at Sound Archives in New Zealand.  So
I was witness to the clever isopropyl drip set-up.  BTW, thanks Marie for
the cassette stock tips - there definitely are some nasty ones around. :o)

Hello, Geeta,

Be aware (or beware) there is a failure mode that some of us are 
calling Loss of Lubricant (or LoL, though it's not a laughing matter) 
that at first looks like Sticky Shed Syndrome (SSS) but isn't. If 
anything, baking may make it worse by driving out more lubricant. The 
best bet is to lubricate the tapes and this has been discussed at 
length here and elsewhere. The person who has done the most in this 
area that I'm aware of is Marie O'Connell now in Mississippi, 
formerly in New Zealand.

Cheers,

Richard
