    摘要： A system and method for trapping electron assisted magnetic recording is disclosed. A magnetic recording system comprises a magnetic storage media, a read/write head, and a power supply for applying a negative DC electrical bias to the magnetic storage media in order to reduce the media switching field during the writing process. Recording is performed by applying an AC magnetic field produced by a write pole and a DC electrical field to assist in the writing. An embodiment of the invention uses a high electrical field to trap free electrons into an unfilled electronic shell of magnetic particles of the magnetic storage media, in particular, (3d) shell of transition elements, (4f) shell of rare earths of lanthanides series, and (5f) shell of actinides series. The trapped electron decreases anisotropy of magnetic particles due to reduced number of Bohr magnetron. As a result, a conventional head is able to write very high anisotropy magnetic storage media.

    摘要： In a recording device, a bit patterned medium comprises a track of bit cells, each settable to one of two distinct bit states. The track comprises two generally parallel rows of bit cells. The bit cells in one row are offset in a down track direction from the bit cells in the other row. A write head spans the two rows. A controller synchronously applies write signals to the write head to set the trailing bit cell covered by the write head as the track moves relative to the write head, and thereby write data to the track. The trailing bit cell covered by the write head alternates from being in one row to being in another row. Read sensors are positioned to independently read bit cells in respective rows, as the track moves relative to the write head along the down track direction.
