The positive definite solutions of the matrix equation X-A~*A~(-α)A-B~*X~(-β)B=I, α,β∈(0,1] were investigated. Necessary and sufficient conditions for the existence of positive definite solutions were derived, which generalize the existing related results. A necessary condition for the existence of the equation to have only a solution and the iterative formula for this solution were obtained. Finally, we got an inverse iterative method for solving the equation.
