<p>In a magnetically recording disk system according to the present invention, during rotation of the disk which generates a higher air pressure (n atm.) at the gap between the slider supporting a head thereon and the disk surface than the ambient air pressure so as to float the slider from the disk surface, a partial pressure of a vapor recalcitrantly released, by heat of the operation of the disk, from an organic material, such as silicone, constituting the recording disk system, is kept lower than 1/n of saturated vapor pressure of the released material. The head slider may be provided with a heater to heat the slider during the disk rotation warmer than the ambient air temperature, preferably by 3 to 15 DEG C higher at the air gap, so that the saturated vapor pressure can be higher at the air gap than without the heating. An enclosure containing the disk, the head/slider and other constituent members is preferably provided with ventilation holes, a first one on which is provided on a side radial to the disk, and a second one on a side axial to the disk, so that the released vapor is exhausted by radial air flow caused from the disk rotation. There is no head crash resulted from a deposition of vapor recalcitrantly released from silicone, on a slider surface facing the disk; accordingly, highly reliable magnetic disk system of enhanced recording density is achieved owing to decreased air gap. <IMAGE></p> |
