The present disclosure generally relates to a tape 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 disposed on a substrate. Each pair comprises a null shield disposed between the write transducer and the read transducer. One or more of a position between the write transducer and the read transducer of each pair, a width, a height, a thickness, and a permeability of the null shield is adjusted to create a null region, and the read transducer is disposed in the null region. The SGV module is configured to write data to a tape using the write transducer of each pair and read verify the data written on the tape using the read transducer of each pair such that the write transducer and read transducer of each pair are concurrently operable.

The present disclosure relates to read head apparatus, and methods of forming read head apparatus, for magnetic storage devices, such as magnetic tape drives (e.g., tape drives). In one implementation, a read head for magnetic storage devices includes a lower shield, an upper shield, one or more lower leads, and a plurality of upper leads. The read head includes a plurality of read sensors, each read sensor of the plurality of read sensors including a first antiferromagnetic (AFM) layer. The read head includes a plurality of soft bias side shields disposed between and outwardly of the plurality of read sensors. The read head includes a plurality of second AFM layers disposed below the plurality of soft bias side shields along a downtrack direction.

A magnetic head includes a main pole configured to serve as a first electrode, an upper pole containing a trailing magnetic shield configured to a serve as a second electrode, and an electrically conductive portion located in a trailing gap between the main pole and the trailing magnetic shield. The electrically conductive portion is not part of a spin torque oscillator stack, and the electrically conductive portion includes first and second electrically conductive, non-magnetic material layers. The spin torque oscillator stack is coupled to the first electrically conductive, non-magnetic material layer. The main pole and the trailing magnetic shield are electrically shorted by the electrically conductive portion across the trailing gap between the main pole and the trailing magnetic shield such that an electrically conductive path is present between the main pole and the trailing magnetic shield through the electrically conductive portion.

The present disclosure is generally directed towards magnetic recording systems comprising a dual free layer (DFL) read head and a magnetic recording head having stable magnetization. The magnetic recording head comprises a main pole disposed at a media facing surface (MFS), and a plurality of shields, such as a lower leading shield, an upper leading shield, a pair of side shields, and a trailing shield. Each of the shields individually comprises a first leg disposed at and parallel to the MFS and a second leg coupled to the first leg, the second leg being recessed from the MFS. When the kind of magnetization initialization needed by the DFL read head is applied to the magnetic recording head during the manufacturing process, the second leg of each of the shields of the magnetic recording device causes the magnetization directions of the shields to individually switch to a stable state.
