Investigations on aligned HgBa{sub 2}CaCu{sub 2}O{sub 6+{delta}} (Hg-1212) powder were performed by measuring magnetization parallel and perpendicular to the applied magnetic field as a function of temperature, field, and the field orientation in the irreversible regime. The anisotropy ratio {var_epsilon}{approx_equal}1/5 is found indicating that Hg-1212 is one of the least anisotropic materials among the technically important high-{ital T}{sub {ital c}} superconducting families. The scaling results for the magnetic field and the in-plane and the out-of-plane critical current densities agree precisely with the collective pinning theory and its scaling approach for anisotropic materials. {copyright} {ital 1996 The American Physical Society.}
