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 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.
摘要翻译：保护器突起形成在并入记录介质驱动器（例如硬盘驱动器）中的磁头滑块上。允许保护器突起与安装在头滑块上的头元件前面的记录介质上的污染物碰撞。可以防止头部元件与保护器突起后面的污染物碰撞。保护器突起位置尽可能靠近头部元件。即使具有较小的保护器突起，前后支撑突起接触记录介质，以将滑块体保持在记录介质的表面上方。可以防止在滑块体和在记录介质表面上扩散的润滑剂之间的吸附作用的增加。较小的保护器突起使得头元件能够在读/写操作时尽可能接近记录介质。
