Heat-Assisted Magnetic Recording for 3 TB/platter

In this work we present recording data taken on a spin-stand using Heat- Assisted Magnetic Recording (HAMR) components. In HAMR, the laser current (applied to assist writing onto the media) determines the track width. First, we show how to optimize the laser current for a given track density. Maximu...
