A disk drive for storing information representing data includes a base, a spindle rotatably attached to the base, and a plurality of disks having magnetizable disk surfaces attached to the spindle. The disk drive also includes a plurality of read/write transducers for writing to and reading from the plurality of magnetizable disk surfaces, and a cover attached to the base. The cover and base form a substantially sealed disk enclosure. The disk enclosure is substantially filled with a mixture of gases including an oxygen portion in the range of 0.1-3% of the mixture, and a low-density gas portion.

Method and apparatus for prevention of Fe contamination with oxygen mixture in a hard disk drive

In one embodiment, a method of manufacturing a magnetic disk includes rotating a magnetic disk, supporting a floating head on the rotating magnetic disk, the floating head having a slider body and an element unit formed on a trailing edge of the slider body, contacting a floating surface of the slider body with the magnetic disk, and protruding a portion of the floating head toward the magnetic disk due to application of power to a heater element within the element unit, wherein the element unit is positioned away from the magnetic disk. In another embodiment, a floating head includes a slider body comprising AlTiC, an element unit positioned on a trailing edge of the slider body, the element unit having an initial recess amount of at least about 4 nm, and a heater element positioned within an alumina protective film of the element unit.
