According to one embodiment, magnetic reproducing element for detecting a magnetic field from a magnetic recording medium comprises a sensor film including a perpendicular magnetization film having a magnetization easy axis in a direction perpendicular to a film plane, wherein magnetization in the sensor film tilts upward or downward in an element height direction from the magnetization easy axis while no magnetic field is applied from the magnetic recording medium, and change in anomalous Hall voltage generated in the sensor film is detected, thereby allowing the magnetic field applied from the magnetic recording medium to be detected. Other magnetic reproducing elements and magnetic heads employing magnetic reproducing elements are described as well.
摘要:
To avoid the occurrence of a recording error by suppressing the influence that a magneto-static interaction acting between the pattern dots exerts on a recording process and expand a margin for recording synchronization timing lag or tracking misregistration on the pattern dot. Each pattern dot has a structure in which a plurality of parts having different magnetization reversal fields are bonded with exchange interaction in the in-plane direction of a medium, substrate. The positional relationship between the parts having different magnetization reversal Fields is substantially coincident between the adjacent pattern dots, which are arranged to have a gradient of magnetization reversal field in a track direction or track transverse direction. Further, the recording is performed by adapting a gradient of recording magnetic field to the gradient of magnetization reversal field. Other methods and systems are described as well.

In order to provide a thermal energy assisted medium capable of improving anti-sliding reliability over long periods of time in low flying head conditions, while also maintaining a high SNR, a unique medium is proposed. A soft magnetic layer is formed on a substrate, a soft magnetic layer is formed thereon via a non-magnetic intermediate layer, and an intermediate layer, a crystal oriented control intermediate layer, an artificial lattice intermediate layer having an artificial lattice film in which a first layer comprising Co and a second layer comprising Pt and Pd are laminated repeatedly to form a recording layer, and a cap layer and an lubricating layer are formed. The concentration of Pd comprising the second layer is from about 20 atomic % to about 40 atomic %. Other mediums and systems are also described.
