関連出願に対する相互参照
本件出願は、「近接場トランスデューサを含む構造および関連する層(STRUCTURES INCLUDING NEAR FIELD TRANSDUCERS AND ASSOCIATED LAYERS)」と題されて2013年6月24日に出願された米国特許仮出願第61/838,407号の優先権を主張するものであり、これらの開示は引用によりここに援用される。
近接場トランスデューサ(NFT)を含む装置が開示され、NFTは5つの露出表面を有するペグを含み、ペグは第1の材料を含み、装置はさらに、上方構造と、ペグと上方構造との間に位置決めされる少なくとも1つの相互混合層とを含み、少なくとも1つの相互混合層は、ペグの5つの表面のうち少なくとも1つの上に位置決めされ、相互混合層は、少なくとも第1の材料と第2の材料とを含む。
熱アシスト型磁気記録(HAMRという)は、たとえばレーザからの放射を利用して媒体をそのキュリー温度より高い温度まで加熱することで磁気記録を可能にする。たとえばレーザー光線などの放射を媒体の小さな領域(約20nmから50nm)に送り届けるために、NFTが利用される。磁気記録動作時において、NFTはレーザからエネルギーを吸収し、それを非常に小さい領域に集中させる。これにより、NFTの温度を高めることができる。NFTの温度は、約400℃以上に上昇し得る。
