Good example my friend. So how would you explain it? Much like the other post @1983 DDR?, could it have something to do with the die perhaps? Deterioration, abrasion or just a clogged device? Or could it be movement, MD related. To be truthful, I don't know. Seeing the inside lower curve has me leaning in a clogged device, possible stress point? But no, not an RPM.
