摘要： Embodiments of the invention reduce damage to a disk recording medium when a slider flying above the disk recording medium inside a magnetic disk drive comes into contact with the disk recording medium due to slider vibration. In one embodiment, a magnetic head slider includes a front pad, a rear pad, and carbon protective films. The front pad includes a step bearing surface disposed on the side of a leading end and leading side rail surfaces formed on the step bearing surface. The rear pad includes a rear step bearing surface disposed across a deep groove surface from the front pad and a trailing side rail surface formed on the rear step bearing surface. The carbon protective films are formed on regions including vertices of slider corner portions, respectively. The leading side rail surfaces and the trailing side rail surface are formed substantially on the same level. The carbon protective films are harder than a slider base material and have a small coefficient of friction. The films have a film thickness of about 10 nm or more.

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.
