You said just the opposite. On a rotating plate, if two objects are kept at different distances from the centre then they'll have same angular velocity but different linear velocity. This is because the angular velocity is the rate of change in angular displacement, which is same for both the objects.
But for linear velocity we have, v = \omega \times r 
Or simply, v = \omega r
So, the linear velocity of an object is directly proportional to the distance from centre.
THANKS
