Abstract
Embodiments of the present disclosure generally relate to tape drives used for magnetic recording on tapes. Tape drives use tape heads that comprise a read head, a write head, and an additional head that may be a write head or a read head. The tape head is fabricated over a common substrate with the first head being formed first, followed by a shield layer, followed by the second head, followed by another shield layer, and finally followed by the third head. Fabricating the tape head over a common substrate is cost effective. The tape head can be wired such that fewer parallel connections between the heads and bond pads are present. As such, cross-talk between the wires and noise is reduced.
