Abstract

Disclosed are design techniques that allow the placement of a servo read head into the same mechanical gap as data write heads for a magnetic tape head. The described designs sufficiently reduce the interference pick up by the servo channel while the data head is writing to allow an accurate servo error signal. The design include limitations on the choice of substrate material, layout/size of the element parts and cable configuration.
