Abstract
A method of making an energy-assisted magnetic recording apparatus is provided. The method comprises the step of aligning a first wafer including a plurality of vertical cavity surface emitting lasers (VCSELs) with a second wafer including a plurality of magnetic recording heads, such that an emitting region of each of the plurality of VCSELs is disposed over a light redirecting structure of a corresponding one of the plurality of magnetic recording heads. The method further comprises the step of bonding the first wafer to the second wafer.
