Correct answer: It uses a laser to heat the surface before writing data.
Brief explanation: HAMR momentarily heats a tiny spot on the disk with a laser to lower the material's coercivity so the recording head can flip smaller, more stable magnetic grains—allowing higher areal density. The other options are not how HAMR works.
