ABSTRACT:
A tape-guide for a magnetic tape is formed by an injection molding process of a mixture material containing 60 to 89% by weight of an ultra-high-molecular-weight polyolefin base resin, having a molecular weight of 800,000, and 4 to 25% by weight of an inorganic additive. The tape guide has an at least partially cylindrical outer surface and an axial end portion, with at least one recess in the end portion. A burr formed by the injection molding hole is located within the recess.
