Write head design for curvature reduction in heat-assisted magnetic recording by topology optimization

HIGHLIGHTS

  • who: O. Muthsam et al. from the University of Vienna, Physics of Functional Materials, Boltzmanngasse, Vienna, Austria have published the research: Write head design for curvature reduction in heat-assisted magnetic recording by topology optimization, in the Journal: (JOURNAL)
  • what: The authors compute the realistic field gradient for a flipped design that follows the model of a state-of-the-art recording head design at the position where the heat pulse is cooling scitation.org/journal/jap penalization parameter k to penalize those densities that are intermediate. To optimize the head, the authors design a . . .
