We consider the problem of placing n points, each one inside its own, prespecified disk, with the objective of maximizing the distance between the closest pair of them. The disks can overlap and have different sizes. The problem is NP-hard and does not admit a PTAS. In the L"~ metric, we give a 2-approximation algorithm running in O(nnlog^2n) time. In the L"2 metric, we give a quadratic time algorithm that gives an 83-approximation in general, and a ~2.2393-approximation when all the disks are congruent.
