Although not pertinent to the OP question, thought I'd reply just for future reference, as the rotor thickness wear limit is very small, one wouldn't be able to detect that threshold by viewing the slotted area. As an example, the front M/T rotor when new is .98" and minimal allowable thickness is .91", so as one can see, once the rotor wears .07" or .035" on each side, the rotor is to be discarded. For those that are interested, the front A/T new 1.10", minimum 1.02", rear new .354", .30" minimum.
This is one reason why cutting the rotors are frowned upon as most shops will return a cut rotor that is actually under the service limit. They don’t mic the rotor to see if the limit has been breached, just cut and return. Most owners don't care as they are saving money by cutting the rotors as compared to new units. I consider rotors as throw away items, in most circumstances, just replace with new.

For future reference, please go and read up on the R1 rotors. The slots are indeed used as a wear reference:

I'll repeat. The R1 concepts use the slots as a unique built-in wear indicator, therefore my statement stands that it's unlikely that the black stripe is a wear indicator. I'm not aware of any other rotors that utilize this form of wear indicator nor did I make any statement as to the accuracy or specificity of this advertised R1 Concept wear indicator.
