ABSTRACT:
A multi-element read/write tape head with low feedthrough includes a multi-element write module with a plurality of write elements. Each write element can write a data track onto magnetic tape as the magnetic tape passes over the write module tape contact surface. The tape head also includes at least one multi-element read module in close proximity with the write module. Each read module has a magnetically permeable substrate, a plurality of read elements built on the substrate top surface, and a cover over each read element and a portion of the substrate top surface. Each read element can read a data track from the magnetic tape as the magnetic tape passes over the read module tape contact surface. The substrate bottom surface is facing the write module thereby providing a low reluctance path for feedthrough from each write element that does not include any read element.
