摘要
We describe the theoretical and experimental investigation of mark shapes in thermally assisted or hybrid recording. The effect of alignment was studied by recording marks on perpendicular TbFeCo media using a commercial recording head and 840 nm laser. We found that mark shapes are primarily controlled through laser/head alignment, and that maximally straight transitions are obtained by placing the laser spot on the leading pole tip near the gap. Simulations of the recording process confirm the experimental findings and are used in conjunction with static write contours to show how transitions form. (C) 2002 American Institute of Physics.
