Abstract
A tape guide drum incorporates a rotary drum, has a lead portion on its outer circumferential surface, and has a rotating axis inclined with respect to a reference surface. The first and second guide pins are arranged at the sides of the tape guide drum so as to wrap a magnetic tape around the drum, and are inclined with respect to the reference surface. The first and second guide pins are arranged so that the magnetic tape enters and exits the drum at elevation angles with respect to the lead portion. The wrap central point of the tape around the tape guide drum is spaced apart from a plane including first and second contact points between the first and second guide pins and the central line of the magnetic tape.
