Brake disc, is this normal?

Hi, noticed on my front brake discs there is a line around the outer edge (about 1cm in from the edge), is this normal? Pics of disc and pad, car is a f80 m3.

Thanks

Ok great, no pulling to the one side or anything, feels perfect still, so nothing to worry about just yet

Wow, thanks for all the comments. I haven’t driven it since posting, but can confirm the pad on the other side is exactly the same (wedge shape) and also has the outer edge wear on the disc too. All rather bizarre.

I’ll pop the wheel off later this week and get a proper look and post pics of both sides! I’m fastidious when it comes to maintenance that I’m aware off, it went into BMW for a service a few months ago and they didn’t mention anything, but more than happy to change discs and pads if they need doing!
