    Abstract
  • The dynamic performance of heat assisted magnetic recording (HAMR) on different media is investigated. Signal and signal-to-noise ratio enhancement are achieved in high coercivity perpendicular media with the aid of laser heating. Linear recording density is increased while saturation write current is lowered. Trailing field partial erasure is observed in lower coercivity media with a ring head, which causes signal reduction with increasing write current or application of a laser. Precautions should be taken against partial erasure in overall recording system optimization of HAMR in order to achieve ultrahigh recording density.
