摘要： A hard-disk drive. The hard-disk drive includes a disk enclosure, a magnetic-recording disk accommodated in the disk enclosure, and a diffusion suppressing film. The diffusion suppressing film divides the space in the disk enclosure into a first space where the magnetic-recording disk is disposed and a second space for retaining a lubricant. The diffusion suppressing film also suppresses diffusion of the lubricant from the second space to the first space.

摘要： Embodiments of the present invention provide a head slider that suppresses accumulation of lubricant droplets on an air-bearing surface due to a backflow, and thus improves reliability of a disk drive. According to one embodiment, a lubricant droplet being adhered to a head slider and accumulated thereon, which are caused by extremely low flying height of the head slider, are prevented from falling onto a recording medium. When velocity of a recording medium at a position where the head slider faces the recording medium is assumed to be v, step depth δ4 at an outflow side of an outflow side rail satisfies, δ4≦0.1125*log10(v)+0.019.

摘要： A magnetic head slider mounted on a magnetic disk unit for supporting a magnetic head that writes and reads information to and from a magnetic disk is constructed such that a depth δs1 from the surfaces of leading and trailing pads, which come into contact with a medium surface when the disk is at rest, to stepped surfaces formed on the air inflow side of the leading pads, a depth δs2 from the contact surfaces to stepped surfaces formed on the air inflow side of the trailing pad and a step depth δs3 from the contact surfaces to the surfaces of side rails are in a relation of δs1≦δs2≦δs3. With this arrangement, the slider can follow the waved medium surface at a low flying height with a small flying height fluctuation, thus realizing high density recording, high reliability and reduced cost of the magnetic disk unit.

摘要： Embodiments of the present invention provide a slider that may suppress contamination from being attached to the flying surface of the slider without influence on reduction of the flying height of the slider. Ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider except for a front rail surface and a center rail surface. According to this, contamination is prevented from being attached to a front step bearing surface, a side step bearing surface, a center step bearing surface and a negative pressure groove where contamination is particularly liable to be attached in the flying surface of the magnetic head slider, so as to suppress destabilization in flying of the slider.

摘要： When a piezoelectric element is deformed in the direction of decreasing a flying height, a pressure at a trailing pad increases, and the flying height of a magnetic head is not efficiently decreased and may be increased conversely in some occasions.A position of contact between a suspension and a dimple is set toward a leading edge with respect to a piezoelectric element, and a pad for generating a positive pressure is disposed between the dimple and the piezoelectric element in addition to a trailing pad. Fluctuations of a positive pressure generated toward the leading edge with respect to the dimple are thus suppressed when the piezoelectric element is deformed.
