A wiring structure of a head suspension including a flexure that supports a head and is attached to a load beam applying load onto the head, includes write wiring and read wiring formed on the flexure and connected to the head, each having wires of opposite polarities and further including a stacked interleaved part which includes segments electrically connected to the respective wires of the write wiring, the segments stacked on and facing the wires through an electrical insulating layer so that the facing wire and segment have opposite polarities, is manufactured by a wiring step, an insulating layer forming step and a stacked interleaved part forming step.

A near-field transducer or heat sink is formed via a first process. The near-field transducer or heat sink is transfer-printed to a read/write head via a second process.

A magnetoresistive (MR) sensor shield shields against both down track and cross-track interference and is formed in a single deposition step. A tail portion of the shield is eliminated by including a non-magnetic material adjacent to opposite sides of a middle portion of the sensor stack.

A magnetic head includes a main pole and a write shield. The write shield includes a bottom shield, a first side shield and a second side shield. The first side shield has first and second sidewalls. The second side shield has third and fourth sidewalls. Each of the second and fourth sidewalls has a top edge farthest from a top surface of a substrate. The top edge of each of the second and fourth sidewalls is parallel to a medium facing surface. A portion of a top surface of the bottom shield, the first sidewall, and the third sidewall define a receiving section to receive a portion of the main pole. The receiving section has a bottom including a first inclined portion, a second inclined portion, and a third inclined portion.

A method of forming a recording head for use with a data storage medium in a data storage device. The method includes forming first and second writers of different target geometries. A first recording measurement is performed on one or more storage media using the first writer. A second recording measurement is performed on the one or more storage media using the second writer. Based on a comparison of the first and second recording measurements to a predetermined quantity, either the first writer or the second writer is selected to be operational in the data storage device.

A method comprises forming a single-crystal-like metal layer on a metal seed layer, the metal seed layer formed on a carrier wafer. The method comprises forming a first bonding layer on the single-crystal-like metal layer. The method also comprises forming a second bonding layer on a dielectric layer of a target substrate, the target substrate comprising one or more recording head subassemblies. The bonding layers may include diffusion layers or dielectric bonding layers. The method further comprises flipping and joining the carrier wafer with the target substrate such that the first and second diffusion layers are bonded and the single-crystal-like metal layer is integrated with the recording head as a near-field transducer.

A row bar for forming magnetic heads includes a row of magnetic head forming portions each having a magnetic head and a cutting portion adjacent to the magnetic heads. A row of bonding pads and a first ELG pad are provided at the magnetic head, a second ELG pad is provided at the cutting portion, both of the first and the second ELG pads are adapted for contacting with a probe during lapping process, and a conductive structure that is higher than surfaces of the first and the second ELG pads is formed at peripheries of the first and the second ELG pads respectively. Due to the conductive structures, a probe used in lapping process will be prevented from shifting from the ELG pads to ensure a stable contact, thereby obtaining efficient and accurate resistance measurement.
