ABSTRACT:
Methods and structures for improving fly height control for thin film write heads utilized in thermally assisted recording are disclosed. Methods include the use of the TAR near field light source to provide a preheating pulse to improve the transient response when moving from one fly height to another prior to writing data. Methods and structures having an additional auxiliary optical heating source to avoid media overheating and replacement of embedded resistive heaters are also disclosed.
