We use a classical result of Golinskii and Ibragimov to prove
an analog of the Strong
Szego Theorem for Jacobi matrices. In particular, we study a class of
Jacobi
matrices and determine necessary and sufficient conditions on the
spectral measure such
that the corresponding parameter sequences lie in the linearly-weighted
l^2 space.
