ABSTRACT:
A tape guide pin for recording and/or reproducing apparatus includes a base body made of non-magnetic material; and a surface layer formed on the base body, made of non-magnetic hard material, the surface layer having the surface roughness whose microscopic tips are rounded. A method of manufacturing the tape guide pin for recording and/or reproducing apparatus includes the steps of: forming a base body of non-magnetic material; forming a surface layer of non-magnetic hard material on the base body; subjecting the base body and/or the surface layer to surface treatment for dimensional accuracy of circumferential surface; and fine-finishing for rounding the microscopic tips of the surface roughness formed by the surface treatment for dimensional accuracy.
