ABSTRACT:
The slide member contains a surface on which a sheet material travels; the surface being composed of a material containing crystals composed predominantly of Si having a size of not larger than 80 microns; the crystals being projected by approximately 0.5 to 3 microns from the surface area of the material and the Si content being in the range from the eutectic range to approximately 30% by weight. The material is a solid solution or a eutectic material containing aluminum as a major component and the crystals composed predominantly of Si. The area where the Si crystals are projected is provided concurrently with an area where the surface is planished or treated so as to give a low coefficient of surface roughness.
The slide member permits a decrease in a coefficient of friction on the surface on which the tape is travelling so that it can maintain its initial conditions for a longer period of time than conventional ones. It also possesses a remarkably high resistance to abrasion so that a pot life of the slide member is lengthened without causing the tape to deviate or depart from the original position on a tape guide or lead. Problems encountered with respect to the rubbing-off of magnetic powders from the tape can also be solved with sounds resulting from an adhesion of the tape to the slide member prevented in an efficient manner.
