    摘要: Ultraviolet rays are radiated over a lubricant film formed on the surface of a recording medium such as a hard disk. The recording medium is then subjected to exposure to bases. The radiation of the ultraviolet rays allows the lubricant film to uniformly spread over the surface of the recording medium. The repellency can be enhanced over the surface of the recording medium. The friction can be reduced on the recording medium. Moreover, when the recording medium is exposed to the base, organic acid existing on the surface of the recording medium and/or in the lubricant film can be transformed into salt. The organic acid can be washed off or removed from the surface of the recording medium and/or out of the lubricant film in this manner. Less organic acid greatly contributes to prevention of generation of corrosion mounds on the recording medium over a longer period.

    摘要: A protection film is layered over the trailing or outflow end surface of a slider body in a head slider for a recording medium drive. A head element is embedded within the protection film. The head element generates heat in response to the supply of an electric current. The heat causes thermal expansion of the protection film. The tip end of the head element thus excessively approaches the recording disk beyond the medium-opposed surface of the head slider. The flying height of a protection protuberance is set smaller than a flying height of the head element even when the protection film suffers from thermal expansion. The protection protuberance is allowed to trace an orbit closer to the recording medium than the orbit of the head element. The protection protuberance is allowed to collide against obstacles on the recording medium in front of the head element.

    摘要: 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.
