The authors introduce a new type of geometric mean of two positive definite (under certain conditions, positive semidefinite) matrices and describe its most important properties. This new concept of a geometric mean is also confronted with the mean introduced by \textit{T. Ando} [Topics on operator inequalities (1978; Zbl 0388.47024)].
