Pulsed write current adapted for use with a field maintenance current in a data storage device










Image Number 7 for United States Patent #6650493.

An apparatus and method for writing data to a magnetizable recording medium in the form of spaced-apart magnetic flux transitions forming magnetization vectors having alternating magnetic orientations and selected lengths. A write element adjacent the medium includes a leading edge and a trailing edge forming a write gap which, when the write element is activated by an electric current, provides a write field for selectively magnetizing the magnetizable medium. A write driver circuit is responsive to a data input stream in providing a write current activating the write element, the write current comprising a pulse current in a phased relationship with a continuous current.
