Machining slotted rotors

I was told it was because the material of the pads versus the material of the rotors cause a little magnetism so when it sits, the pads stick to the rotors and they end up "warped".

My old rotors and brakes (OEM) did the same thing. I was hoping a different combination would help but not so much.

I didn't see why they couldn't be machined, if the shop goes slow but just curious if anyone else had experience with that.

By any chance, was the parking brake engaged during this period of sitting? It is possible when the car was parked, the rotors were hot and if the pads were allowed to stay in contact with the rotor they would have pulled the heat from that spot and could in theory cause warpage. I'm not buying the magnetism theory.
