Most disks show clear evidence of dust scattering through their unidirectional polarization pattern typically at the shorter wavelength of $\\sim 870 \\mu$m. However, certain disks show an elliptical pattern at $\\sim 3$mm, which is likely due to aligned grains. With HL Tau, its polarization pattern at $\\sim 1.3$mm shows a transition between the two patterns making it the first example to reveal such transition.
