We formulate the massive overlap fermions on anisotropic lattices. We find that the dispersion relation for the overlap fermion resembles thecontinuum form in the low-momentum region once the bare parameters are properlytuned. The quark self-energy and the quark field renormalization constants arecalculated to one-loop in bare lattice perturbation theory. We argue that massive domain wall quarks might be helpful in lattice QCDstudies on heavy-light hadron spectroscopy.Comment: 21 pages, 5 figures, one reference added compared with v.
