Almost! A solid bit of vinyl, perhaps with an aluminum disk embedded (to help the pad keep its shape), would work quite well.
Hi Ralph,
Do you think something like this might be what you may have had in mind?
The SPEC AP-UD1
a made in Japan. This is the updated one, that has the center recessed to accommodate the record label. It's circumference, if I remember correctly, is also just slightly less than the original AP-UD1, to allow you to remove the record while still spinning so that you do not lift the platter mat off along with the record.
The following links talk mostly of the original SPEC AP-UD1. I haven't found much info on the new and improved, updated SPEC AP-UD1
a as it is still pretty new.
Here is a link of one for sale

Here is a link of Jeff Day commenting on the original SPEC AP-UD1. The AP-UD1
a is the updated mat and is what you would want to have.

I happen to have two of the AP-UD1
a mats. I had ordered one, and simultaneously, my wife ordered me one as a present, not knowing I had already order it myself. I only have one turntable, so if anyone is interested in buying my second unused mat, let me know. I paid $350 ( it came to $372 with tax and shipping ). Make me a reasonable offer and it's yours
Best wishes,
Don
