Stove / range

So I am wondering if anyone has ever seen an electric stove or range with this type of burner? They look like 45 rpm records: circular with ridges. I haven't been able to look too closely at the back of the stove so I can't even tell you want the brand is. It looks to be 1970s vintage and the only words I can read are "Special Edition" on the backsplash. Not even sure how to clean it...

ADVICE REQUESTED:
What kind of stove is this and how do you clean it?
