    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.

    摘要翻译： 保护膜层叠在用于记录介质驱动的磁头滑块中的滑块体的尾部或流出端表面上。 头部元件嵌入保护膜内。 头元件响应于电流的供应而产生热量。 热量导致保护膜的热膨胀。 因此，头部元件的尖端过度地接近磁头滑块的介质相对表面之外的记录盘。 即使当保护膜遭受热膨胀时，保护突起的飞行高度也被设定为小于头部元件的飞行高度。 允许保护突起跟踪比头元件的轨道更靠近记录介质的轨道。 允许保护突起与头元件前面的记录介质上的障碍物碰撞。

    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： A magnetic head slider has a plurality of rail planes to generate a floating force by using an air flow passing through a region between a group of the rail planes and a magnetic disk rotated at a constant rotating speed, and the slider floats up into the air according to the floating force. Also, the slider has a first pad arranged near an air inflow end of one rail plane and a second pad arranged near an air outflow end of the same or another rail plane, and a height of the first pad and a height of the second pad respectively range from 20 to 50 nm. Therefore, a coefficient of a friction between the pads and the magnetic disk can be reduced, and the wear of the pads can be prevented. Also, the contact of an electro-magnetic transducing device attached to the air outflow end of the rail plane with the magnetic disk can be prevented.

    摘要： A magnetic head slider comprises a slider body comprising a base portion made of an altic material and an element-forming portion, made of alumina, having formed thereon magnetic conversion elements. Slider-flying rails protruding beyond the surface of the slider body are provided. A first protection film is formed on the surface of the slider body to cover a boundary between the element-forming portion and the base portion to thereby prevent a lubricant of a magnetic disk from depositing on the boundary between the base portion and the element-forming portion. Second protection films are formed on the surfaces of the slider-flying rails to protect the magnetic conversion elements from being corroded and damaged. Further, when pneumatic bearings are provided on the slider-flying rails, third protection films are formed on the surfaces of the pneumatic bearings.
