    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.

    摘要： An object of the invention is to provide an anthracene derivative having characteristics peculiar to anthracene such as e.g., high carbon density, high melting point, high refractive index and fluorescent properties for ultraviolet rays, etc., and reaction diversity that results from the bisphenol structure, and a process for producing the same. Disclosed is an anthracene derivative represented by the following general formula (1): in the formula (1), X and Y each independently represent a hydroxyaryl group. The aforementioned X and Y are preferably a hydroxyphenyl group. In addition, the anthracene derivative can be produced by a process including allowing at least one compound selected from phenols and anthracene-9-carboaldehyde to react in the presence of an oxygen-containing inert organic solvent and an acid catalyst.
