Abstract
An HAMR NFT pin and main body structure comprising a pin material with high index of refraction and low absorption coefficient is disclosed. The disclosed NFT pin provides a comparable media absorption efficiency to the conventional Au pin while improving on overall NFT reliability. The protrusion of the NFT pin is reduced and overall life of the writer is prolonged. The main body may comprise any noble metal or metal alloy suitable for achieving optical resonance in an HAMR NFT. The cladding material may be selected such that its coefficient of thermal expansion closely matches the coefficient of thermal expansion of the pin material.
