Abstract: Means for improving separation between a transducer operating surface and a moving record media. Nonuniform pressure distribution between the media and the operating surface produces a cocking tendency in the media increasing upstream separation and decreasing downstream separation over the processing zone in the transducer. This invention recognizes that the cocking tendency is caused by a region of lower than ambient pressure near the point where the media draws away from the operating surface, and provides means for supplying ambient pressure at that point. In a preferred embodiment, the means comprises a transverse slot extending beyond the side edges of the media.
Abstract translation: 用于改善换能器操作表面和移动记录介质之间的分离的装置。 在介质和操作表面之间的不均匀的压力分布在介质中产生翘起倾向，增加了上游分离并减小了在换能器中的处理区域的下游分离。 本发明认识到，起动趋势是由介质从操作表面离开的点附近的低于环境压力的区域引起的，并提供在该点处提供环境压力的装置。 在优选实施例中，装置包括延伸超出介质侧边缘的横向槽。

Abstract: An air bearing supports the magnetic recording tape of a magnetic tape unit as the tape moves in a curved path, the air bearing having a plenum chamber connected through an orifice to a high-pressure source of air, the pressure magnitude of the source being such that over the operating range of the bearing, the mass rate of air flow into the plenum chamber, and thus out of the bearing to support the tape, is substantially constant.
