Abstract
The free Baker-Akhiezer modules on rational varieties obtained from CP1×CPn–1 by identification of two hypersurfaces are constructed. The corollary of this construction is the existence of embedding of meromorphic function ring with some fixed pole into the ring of matrix differential operators in n variables.

Key words: commuting differential operators; Baker-Akhiezer modules.
