Magnetic tape guide apparatus

摘要

A magnetic tape guide apparatus which can guide not only a magnetic tape having an applied magnetic layer thereon but also a magnetic thin metal film magnetic tape with a high transport performance is disclosed. The magnetic tape guide apparatus comprises a magnetic tape guide drum or a guide pin having a cylindrical profile for guiding a magnetic tape along a magnetic guide face provided by an outer circumferential face thereof. The magnetic tape guide face is formed as a roughened face wherein the height delta of crests is selected within the range of 0.2 mu m to 3.0 mu m and the pitch x of the crests is selected so that it satisfies 0.050 mm
