    Abstract: In one implementation, the disclosure provides a method comprising detecting one or more areas of a storage medium having a data pattern with a plurality of consecutive bits, where the consecutive bits have the same polarity. The method further comprises encoding additional information on a section of the one or more detected areas, where the section of the one or more detected areas has a signal to noise ratio (SNR) higher than SNR of the other areas of the storage media.

    Abstract: A recording head for writing data on tracks of a data storage medium is provided. The recording head includes a writer having a write pole and a trailing shield. The write pole includes a pole tip configured to write on the tracks of the data storage medium. The recording head also includes first and second writing-assistance wires positioned between the pole tip and the trailing shield in a down-track direction to enable a writing-assistance current to be provided to produce an assist magnetic field that augments a write field produced by the write pole.
