ABSTRACT:
New helical recording scanner architectures and transducing methods provide a consistent track pitch for helical tracks despite positional errors in placement of transducing elements (or sets of transducing elements) from their nominal positioning. The new scanners (85) are rotatable scanners having a vertical direction parallel to an axis of rotation of the scanner. Both first and second transducing elements are mounted on the scanner, and a tape drive (30) which comprises the scanner also includes a transport system for transporting magnetic tape (31) proximate the rotatable scanner in a manner so that information is transduced in helical tracks by the transducing elements during revolutions of the scanner. A width of the transducing elements and the nominal positioning of the transducing elements with respect to the vertical direction are selected so that the tracks transduced by the first transducing element and the second transducing element have a desired pitch regardless of an error between the nominal positioning and actual positioning of at least one of the first transducing element and the second transducing element.
