Microscopy Images of 2-bit-per-dot Patterned Media

Caption: Atomic force microscopy (left) and magnetic force microscopy (right) images of the two-bit-per-dot patterned media after AC demagnetization in both in-plane and out-of-plane directions. The four possible magnetic configurations are randomly distributed. Examples of bit configurations are highlighted and labeled as A, B, C and D in reference to the magnetic configurations depicted on the left of the figure.
