摘要： A first protection layer is overlaid on the surface of a recording layer in a recording medium. A second protection layer is overlaid on the surface of the recording layer at a position adjacent the first protection layer. The second protection layer has a composition different from that of the first protection layer. The first and second protection layers have different compositions, so that the overall protection layer is allowed to have an unequal property. The second protection layer may have a hardness higher than that of the first protection layer. A higher hardness of the second protection layer serves to avoid damages on the surface of the recording medium rather than the first protection layer. The recording medium can reliably be protected from collision or contact of an object.

摘要： A method of texturing includes the process of enhancing the hydrophilicity on the surface of a substrate for a recording medium. A texture is then formed on the surface of the substrate with an aqueous slurry in which abrasive grains are dispersed. The surface of the substrate is expected to exhibit an enhanced property of wetness to the aqueous slurry. The aqueous slurry easily spreads over and contacts the surface of the substrate even from the initial stage of the process. The abrasive grains in the aqueous slurry are allowed to uniformly spread over the surface of the substrate. Establishment of the texture can be started on the surface of the substrate at an earlier stage of the process. Even with the abrasive grains of a smaller grain size, a fine and uniform texture of a predetermined surface roughness can be established on the surface of the substrate within a shortened period. Increase in the operating period of abrasion can remarkably be suppressed irrespective of the reduced size of the abrasive grains.

摘要： A projection serves to space the air bearing surface apart from the surface of a recording disk when the recording disk stands still. The contact area can be reduced between a flying head slider and the surface of the recording disk. When the flying head slider inclines downstream around the tip end of the projection in response to a reverse rotation of the recording disk at the beginning of the rotation, the flying head slider allows a rugged surface to contact the surface of the recording disk at the outflow end thereof. The effect of meniscus or adsorption cannot be intensified between the lubricating agent or oil and the air bearing surface, namely, the flying head slider. Accordingly, it is possible to reliably avoid failure in starting the recording disk to rotate. Less torque of the spindle motor allows the recording disk to normally start rotating.
