  We calculate the quasi-uniform gravitational field of a disk in the
weak-field approximation and demonstrate an inappropriateness of preceding
results. The Riemann tensor of this field is determined. The nonexistence of
the uniform gravitational field is proven without the use of the weak-field
approximation. The previously found difference between equations of motion for
the momentum and spin in the accelerated frame and in the quasi-uniform
gravitational field also takes place for the disk. However, it does not violate
the Einstein equivalence principle because of the nonexistence of the uniform
gravitational field.
