• "Just like the goldfish growing to fill the space not really! that second CCC is like a gas that is expanding to fill the space...the poor little cupcake molecules are losing their coercivity and dissolving into a sheet of entropy!"
• "Quantitatively if you so wish i.e., what is the coercivity of the magnetic field required to change the state of an individual bit on the disc."
• "Due to the crystalline anisotropy, the ultra-fine barium-ferrite particles have high coercivity for superior performance high density recording."
