ABSTRACT:
A magnetic transducer device for maintaining improved recording tape to transducer head contact at reduced contact pressure. A pair of vertical outrigger bars are mounted on either side of the transducer head transverse to the path of the recording tape. The surfaces of the vertical bars facing the recording tape are located slightly below the plane of the outer surface of the transducer head thereby maintaining a constant, shallow wrap angle of the recording tape over the transducer head. Furthermore, a second pair of horizontal outrigger bars are mounted on either side of and adjacent to the transducer head along an axis transverse to the path of the recording tape. The surfaces of these horizontal bars facing the recording tape are located in substantially the same plane as the outer surface of the transducer head, thereby providing support for the recording tape when the transducer head is positioned near the edge of the tape and preventing the edge of the tape from lifting from the head due to its upward flex curvature.
