  A stack of coated conductors is a perspective configuration for various
applications of high temperature superconductors. We present an efficient fast
Fourier transform-based numerical method for magnetization problems for a stack
of flat films of the same (arbitrary) shape and compare it with the recently
proposed finite element methods. For stacks containing a large number of
densely packed films an accurate solution can be obtained as a properly
rescaled solution for a stack of only several films. For an infinite stack the
problem simplifies and becomes similar to that for a single film.
