Abstract:
The present disclosure generally relates to a tape head and a tape head drive including a tape head. The tape head comprises at least one same gap verify (SGV) module comprising a plurality of write transducer and read transducer pairs. Each write transducer is coupled to writer bonding pads via writer leads, and each read transducer is coupled to reading bonding pads via reader leads. An isolation shield is disposed between the write transducer and read transducer such that the isolation shield is disposed between each writer lead and each reader lead. The isolation shield acts as a Faraday cage to reduce cross-talk between the write and read transducers. The SGV module is configured to write data to a tape using the write transducers and read verify the data written on the tape using the read transducers such that the write transducers and read transducers are concurrently operable.
