In one embodiment, the write functional section includes a coil conductor, second soft magnetic film pattern and first soft magnetic film pattern that cover the coil conductor from top and bottom and are magnetically coupled to each other, and a main magnetic pole piece determining a track width. The read functional section includes a reading element sandwiched between two magnetic shield films. A pedestal magnetic pole pattern is formed at the frontal end position of the first soft magnetic film pattern.

摘要： In one embodiment, a data storage system includes a magnetic head having a main magnetic pole and a wrap around shield positioned around the main magnetic pole at an ABS thereof, a magnetic medium, a drive mechanism for passing the magnetic medium over the magnetic head, and a controlling mechanism electrically coupled to the magnetic head for controlling operation of the magnetic head that initiates rewriting of information of a recording track of the magnetic medium if a recording magnetic field applied to the recording track exceeds a threshold. In another embodiment, a method includes writing data to a first track of a magnetic medium using a magnetic head, determining characteristics consistent with data degradation from tracks adjacent to the first track and far tracks away from the first track using a controlling mechanism, and rewriting data in tracks determined to be degraded due to ATI and/or FTI.
