What copy protection is this

I’ve begun to get serious about chess again andbought a copy of Shredder 7. It appears to be copy protected, but nothing has identified the protection type correctly to allow me to copy it with Alcohol120.

The CD itself has a special track just a little bit in from the outer edge. Can anyone provide guidance on what this copy protection is?

Thanks, Bryar
