摘要： A head slider includes a parallelepiped-shaped slider base having a flat flying surface. A flat first step is formed at an air inlet end of the flying surface to be stepped from the flying surface. A flat second step is formed on the first step to be stepped from the flying surface. A vacuum area is formed at a downstream end of an air flow flowing from the first and second steps on the flying surface. At least one groove is formed on a portion of the first step for introducing air to the vacuum area. The width of the groove at the air inlet end and the width of the groove at an air outlet end can differ from each other. A trailing edge of the first step can be closer to a trailing edge of the slider base than a trailing edge of the second step.

摘要： A magnetic head slider includes a floating surface that is opposed to a disk during the use of the magnetic head slider and that has a front part and a rear part with respect to the direction of rotation of the disk, and an electromagnetic transducer element. A front rail extending in the transverse direction and a pair of rear rails are laid on the floating surface. A plurality of first projections is formed on the front side and the rear side of the front rail. A plurality of second projections is formed behind the plurality of first projections. When the disk is stopped, the plurality of first projections is stationed on the disk but the floating surface is not in contact with the disk. The height of each of the plurality of second projections is smaller than the height of each of the plurality of first projections. When the magnetic head slider is employed in a contact start/stop (CSS) type disk drive, the plurality of second projections prevents the rear end of the floating surface from coming into contact with the disk.

摘要： With a view to providing a head slider which can suppress the adhesion of dust particles to a flying surface of the head slider when the head slider flies and a disk drive employing the same head slider, a head slider in which at least an air bearing portion and a land portion for forming a vacuum area on the flying surface are provided on the flying surface of the head slider, the land portion being formed in such a manner as to have a difference in level so as to be closer by a step to a disk medium than an end surface of the slider base, wherein the water repellency of an end surface of the land portion and the water repellency of the end surface of the slider base are made higher than the water repellency of the air bearing portion. As this occurs, the water repellency of the end surface of the land portion is increased more than the water repellency of the air bearing portion, whereby the water repellency of the end surface of the slider base can be increased more than the water repellency of the end surface of the land portion.

摘要： A disk drive including a negative pressure type head slider having a transducer for reading/writing data from/to a disk having a plurality of tracks, and an actuator for moving the head slider across the tracks of the disk. The actuator includes an actuator arm rotatably mounted on a base of the head slider, a suspension fixed at a base end portion thereof to a front end portion of the actuator arm, and the head slider mounted on a front end portion of the suspension. The head slider includes a front pad having a raised surface and a step surface lower in level than the raised surface, the transducer formed near the air outlet end, and a first groove for generating a negative pressure by expanding air once compressed at the front pad. The bottom surface of the first groove is formed with a plurality of second grooves continuously extending from the downstream side of the front pad to the air outlet end. The second grooves are spaced from each other in the transverse direction of the head slider.

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。

摘要： A head assembly for an information storage device that includes a head slider with a read/write element for reading/recording information to/from a disk and a suspension for supporting the head slider. The suspension includes a generally planar sheet that extends in a longitudinal direction from a first end to second end and an arm attaching portion located near the first end of the generally planar sheet of the suspension. The arm attaching portion is adapted to be attached to a head arm. The suspension also includes a slider attaching portion positioned near the second end of the generally planar sheet of the suspension, where the slider attaching portion extends generally in the longitudinal direction and is surrounded by a generally U-shaped opening in the generally planar sheet. The slider attaching portion faces a securing surface of the head slider. At least one of the slider attaching portion of the suspension and the securing surface of the head slider includes a nonplanar portion, and the head slider and the suspension are affixed to each other at the nonplanar portion, whereby the effects of torsion upon the alignment of the head slider are mitigated by the nonplanar portion. Preferably, the nonplanar portion includes a curved portion.
