The aim of the paper is to prove that the ∗-algebra of all (closed densely defined linear) operators affiliated with a finite type I von Neumann algebra admits a unique center-valued trace, which turns out to be, in a sense,  normal.   It is  also demonstrated that  for no other von Neumann algebras similar constructions can be performed.
