摘要： In a magnetic disk device including a magnetic disk coated with a lubricant, a face of a magnetic head slider, at a trailing side of the slider, is constructed so that all or part of an outer region adjoining other faces is made less wettable than other regions present at the trailing side face. For example, the trailing side face 13 of the magnetic head slider 8 has a protrusion 12 at both upper and lower ends of the face 13. Surface wettability of a face 12a forming the top of one of the protrusions 12 is reduced below surface wettability of other regions (a face 12c orthogonal to the face 12a, and a region 11). In addition, the other regions each have surface wettability that allows any sticking droplets of the lubricant to provide a sufficient wetting spread, but to such an extent that the droplets do not fall.This prevents a wetting spread of the lubricant to an air bearing surface, and hence, a fall of the lubricant from the magnetic head slider. Reliability is therefore enhanced.

摘要： A step height is provided in an upper surface of a nozzle plate. Plural pairs of nozzle holes are provided in the nozzle plate, and thereby a liquid film is formed with fuel liquid columns injected from each pair of nozzle holes. In one nozzle hole, as the step height is placed in the vicinity of the nozzle hole, the direction of the fuel flow is changed to a direction along the surface of the step height, and a swirl flow is formed at its inlet. On the other hand, as the other nozzle hole is away from the step height, thereby a uniform inflow without swirl flow is formed. As a result, the shape of the liquid film is changed to a predetermined pattern liquid film by increase of the pressure.
