[ARSCLIST] Instant Recording Discs, was Re: [ARSCLIST] Record Gunk

[Christie Peterson <cpeterso@xxxxxxxxx>]

Thanks to everyone who responded to my record "gunk," er, palmitic acid 
question.  After careful examination of the surface, I went the Windex 
and distilled water route, with very good success.  The disc cleaned 
right up, does not have any flaking, and, 24 hours after cleaning, does 
not seem to have suffered any ill effects.

Now, I find we can't play this disc (along with about a half dozen 
others that appear to be instant recordings from NBC news) because the 
hole drilled in the middle is too small to fit our turntables.  Since I 
don't know the proper term for the pin in the middle of the platter (and 
since none of the dozen or so audiophile pages I've read on turntables 
mentions it), it's really hard to find information about what to do.  
Again, advice from those in the know will be gratefully accepted.
