Abstract: Solid material gasification method comprises a solution preparation step wherein a first solid material is dissolved in a solvent to prepare a gasification solution, a solvent removal step wherein a second solid material is separated by removing the solvent used to prepare the gasification solution from that solution, and a solid sublimation step wherein the second solid material is gasified by sublimation.

Abstract: A method of making a tetrahedral amorphous carbon (ta-C) film comprises depositing carbon atoms over the surface of an object. The surface of the object is kept exposed to fluorine atoms during the deposition of the carbon atoms. The method allows the fluorine atoms to scatter within the deposited carbon atoms in the tetrahedral amorphous carbon film. The hardness of the tetrahedral amorphous carbon film can be improved in response to an increased content of sp3 carbon bonds included within the tetrahedral amorphous carbon film. In addition, the tetrahedral amorphous carbon film still provides a sufficient repellent performance to water due to the fluorine atoms existing near the exposed surface of the tetrahedral amorphous carbon film.

Abstract: A protector protuberance is formed on a head slider incorporated in a recording medium drive such as a hard disk drive. The protector protuberance is allowed to collide against a contamination on a recording medium in front of a head element mounted on the head slider. The head element can be protected from collision against the contamination behind the protector protuberance. The protector protuberance is located as close to the head element as possible. Even with a smaller protector protuberance, the front and rear support protrusions contact the recording medium so as to hold the slider body above the surface of the recording medium. An increase can be prevented in the adsorption acting between the slider body and a lubricant agent spreading over the surface of the recording medium. A smaller protector protuberance enables the head element to approach the recording medium as close as possible upon read/write operations.
