摘要： Embodiments of the invention provide a slider structure able to lower a flying height compensation ratio caused by a projecting deformation of an air bearing surface of a slider by a flying height control mechanism and afford a change in flying height with a low control power. In one embodiment, a slider is provided with a leading edge, an air bearing surface, and a trailing edge. The air bearing surface includes a front pad, the front pad being made up of a front step bearing surface, leading rail surfaces, and side step bearing surfaces. The air bearing surface also includes a negative pressure groove surface surrounded by the front pad. The air bearing surface further includes a rear pad, the rear pad being made up of a rear step bearing surface formed at the same depth as the depth of the front step bearing surface and positioned on the trailing edge side, a trailing rail surface, an intermediate groove deeper than the trailing rail surface, and a trailing pad surface lying at the same height as the trailing rail surface. The front and both sides of the trailing pad surface are surrounded by the trailing rail surface.

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： Embodiments of the invention improve the power consumption and response speed of a heater for the gap flying height (hg) adjustment, to minimize an influence that the heater has on a life of a read element, and to provide a heater having resistance lines reduced in breaking and ensuring higher reliability. In one embodiment, a read/write element is formed near an air bearing surface (ABS) on a slider, and the circumference of the read/write element is filled with alumina. The read/write element includes an upper magnetic pole piece, a lower magnetic pole piece, a coil, and a resist filling around the coil, and a read element (MR) for performing reading, and an upper shield and lower shield for protecting the read element from an external magnetic field. A heater for adjusting the flying height is provided between the slider and the read/write element but near the read/write element. A temperature gradient relaxing material having a thermal conductivity higher than that of the heater and that of a material (alumina) filling around the heater is formed near the heater.
