MONSTER CD RINGS . How to Remove ?

Going through my massive collection of CDs, I just noticed about a dozen discs with MONSTER RINGs around them. Back in the early 90s I fell for the Stereophile ploy of Monster CD ring tweek. Which was suppose to increase the accuracy of the CD laser reading. Thus giving more information and better sound.

Two quick questions..

1- How the heck do you get the (Monster CD) ring off the disc without ruining the CD ?

2- If I do use these CDs with the Monster rings on the disc. Can it damage or stress the CD motor mechanism because of the extra weight spinning ?

Thank you to all who help.
