Abstract
A tape head assembly comprises a transducer head having plural arrays of transducing elements, the transducing elements comprising at least one of write elements and read elements. The tape head assembly further comprises a set of conditioning elements, the conditioning elements comprising at least one of write drivers and read amplifiers. Multiplexing circuitry selectively couples the conditioning elements to one of the plural arrays of transducing elements.
