Apparatus and method of controlling tape wander using head zenith biasing

A tape guide device (10, 110, 210) has a support base (22) and a pair of tape guides (12, 14, 112, 114, 212, 214) carried by the base (22) on spaced and substantially parallel axes (33, 35). Each tape guide (12, 14, 112, 114, 212, 214) has a slide contact section (40, 42, 140, 142) and at least one...

Summary:A tape guide device (10, 110, 210) has a support base (22) and a pair of tape guides (12, 14, 112, 114, 212, 214) carried by the base (22) on spaced and substantially parallel axes (33, 35). Each tape guide (12, 14, 112, 114, 212, 214) has a slide contact section (40, 42, 140, 142) and at least one tape guide element (26, 30, 126, 130) for engaging one edge (38) of a ribbon tape (20) movably supported therealong. A magnetic head (16, 116, 216) has a tape sliding surface (18, 118, 218) supported for engagement with the ribbon tape (20), the tape sliding surface (18, 118, 218) presented for engagement with the ribbon tape (20) at a Zenith angle (36) relative to the tape guide axes (33, 35). Application of travel tension on the tape (20) as it runs over the magnetic head (16, 116, 216) and tape guides (12, 14, 112, 114, 212, 214) creates a transverse force on the tape (20), biasing the tape one edge (38) against the tape guide elements (26, 30, 126, 130) of the pair of tape guides (12, 14, 112, 114, 212, 214) so as to reduce tape wander. A method for imparting such a bias via a Zenith angle (36) positioning of a magnetic head (16, 116, 216) in relation to the tape guides (12, 14, 112, 114, 212, 214) is also disclosed.
