recessed center in old turntables platters ... why


why old turntable platters (like garrard for example) has a recessed center for labels and new ones (like VPI) don't?, I supposse that what is good for records in the 60s or 70s should be good now right?. would like to hear your opinions about this matter. Thanks in advance

Hi, not just that recessed area. Im talking about the one that is around 3.5" wide. Is supposed to be the same diameter as the record label to hold the "thicker part" of the record that contains the label, but not quite sure that this is a necessity.
VPI tables do have recessed platters. I've owned a Scout and a Classic and both platters had recessed centers.
