According to one embodiment, a magnetic head for at least one of reading and writing data on to a magnetic data storage media. The magnetic head comprises a substrate, an at least partially crystalline alumina layer formed on the substrate, at least one of a write transducer and a read transducer formed on the substrate, and a surface for engaging the magnetic data storage media. In another embodiment, a method for forming an at least partially crystalline alumina film. The method comprises providing a substrate, and depositing alumina onto the substrate at an ambient temperature to form the at least partially crystalline alumina film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Head comprising a crystalline alumina layer","description":"A magnetic head produced at low ambient temperatures that comprise a crystalline alumina layer for increasing the durability of the head is provided.
