Flying Height Control Using Dual Thermal Protrusions in Heat Assisted Magnetic Recording (HAMR)
Conference-paper 2012 EN
Thermal flying height (TFC) control technology has been used in the past few years to achieve a lower flying height for higher storage areal density. In this paper, a slider with dual thermal protrusion, one produced by the laser used to heat the disk in HAMR and the other one used for TFC, is programmed with feedback control to reduce the flying height modulation (FHM) due to disk waviness and to…
