  We describe a new class of minimal link diagrams. This class includes certain
alternating diagrams, the standard diagrams of all torus links, and numerous
homogeneous diagrams whose minimality has not been proven before. Besides, we
describe a new larger class of link diagrams with the least number of Seifert
circles among all diagrams of a given link. Our approach refers to the
Morton-Franks-Williams inequality.
