Abstract
A recording head includes a structure such as a near-field transducer formed of a noble metal. An adhesive layer is formed over a surface of the structure. The adhesive layer includes alumina and is 4 nm or less in thickness. A silicon dioxide layer is formed over the adhesive layer. The adhesive layer bonds the silicon dioxide to the structure.
