Abstract

PURPOSE: To prevent any stick slip, even if a fixing guide plate is wetted with dewdrops, by roughing the surface of the guide plate, which is to contact with a magnetic tape, such that its leading end is formed with generally semispherical projections.
CONSTITUTION: The surface of such a fixing guide body 1, which is to contact with a magnetic tape, as is made operative to guide the running operation of the magnetic tape is cut to form saw-tooth projections A to have a surface roughtness of 6 to 150 microns. The tips of the projections A are buffed with semicircular projectins B which have smooth soundness. In case the fixing guide has its surface wetted with dewdrops, the adhesion due to the surface tension of water becomes the higher as the surface finish roughness is the smaller so that the contact load of the magnetic tape upon the fixing guide is increased. As is described in the above, the surface tension of water exerts influences upon thecoefficient of friction between the magnetic tape and the fixing guide, but the coefficient is reduced by increasing the surface roughness as in the aforementioned projections B so that the stable tape running operation can be ensured without any stick slip even under the dew-wetted conditions.
