The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface (MFS), a trailing shield at the MFS, and a heavy metal layer disposed between the main pole and the trailing shield at the MFS. Spin-orbit torque (SOT) is generated from the heavy metal layer and transferred to a surface of the main pole as a current passes through the heavy metal layer in a cross-track direction. The SOT executes a torque on the surface magnetization of the main pole, which reduces the magnetic flux shunting from the main pole to the trailing shield. With the reduced magnetic flux shunting from the main pole to the trailing shield, write-ability is improved.

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 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 closure, a substrate, and a plurality of write transducer and read transducer pairs. The write transducer and the read transducer of each pair are spaced a first distance in a first direction of about 5 μm to about 20 μm.

In some embodiments, the SGV module head assembly is further configured for dynamic tilting to enable correcting of mis-registration caused by tape lateral dimension changes.
