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 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 flying head slider comprises a flying surface opposed to the surface of the magnetic disk. Inner and outer rails are formed on the flying surface. Air bearing surfaces (ABS) are defined on the inner and outer rails. A magnetic head element is embedded in the outer rail at the protection layer attached to the end surface of the slider body. A splay is formed on the air bearing surface (ABS) of the outer rail. When the head slider takes off from the surface of the magnetic disk, the head slider takes a slant attitude with the protection layer nearest to the surface of the magnetic disk. The splay in the outer rail serves to avoid the protection layer from colliding with the surface of the magnetic disk even when the head slider rolls. The head slider is capable of making the magnetic head element thereon approach the surface of the magnetic disk as much as possible even if the head slider is expected to change its attitude.

摘要： A head assembly which can prevent an increase in the frictional force between the head and the recording medium, even if the spindle motor is rotated in the reverse direction during start-up of the disk drive. The head assembly includes a suspension having a roundedly bent portion for generating a spring load and a gimbal located on the suspension. A head slider is mounted on the gimbal. The head slider has an air bearing surface, an air inlet end, and an air outlet end. The spring load of said suspension is applied to the head slider at a load point that is offset from a center of gravity of said head slider. Preferably, the offset load point is located between the center of gravity of the head slider and its air inlet end. Additionally, the head slider preferably includes several pads extending from its air bearing surface, and the offset load point can be located at the center of gravity of the pads (as opposed to the center of gravity of the head slider in its entirety). There are two preferred configurations for realizing the offset load point of the present invention: (1) using a reinforcing plate connected to the suspension, and a pivot formed on the reinforcing plate and kept in pressure contact with the slider mounting portion of the gimbal, such that the pivot applies the spring load to the head slider; and (2) bending the gimbal at a neck portion thereof by a given angle to apply the spring load.

摘要： A method of obtaining a limit glide height in flying a head above a recording medium being rotated. The first step is storing the medium and the head into a chamber, stepwise reducing an air pressure in the chamber, and measuring a flying height of the head and a frequency of contact of the head with the medium in each step. The second step is performing head vanish to polish away projections on the medium by means of the head under such conditions that the head at least intermittently comes into contact with the medium. The third step is reproducing the air pressure in each step in the first step, and again measuring a flying height of the head and a frequency of contact of the head with the medium in each step. The final step is comparing a measured value of the frequency of contact in each step in the first step and a measured value of the frequency of contact in each step in the third step, and obtaining the limit glide height defined as a flying height of the head corresponding to the step in which a rate of change in the frequency of contact becomes largest.

摘要： A magnetic disk storage apparatus comprising a rotary actuator which prevents head positioning error resulting from vibration and impact. Since head positioning error is generated when the enclosure makes rotating movement due to translational vibration input due to vibration, a vibration proof mechanism consisting of a plurality of vibration proof supporting members are provided between the enclosure and frame. The plural vibration proof supporting members are disposed so that the linear moment around the gravity center of the enclosure is balanced against translational external force applied to the enclosure.
