N2 - With the increase of areal density in hard disk drive (HDD), the mechanical spacing between magnetic head and disk has decreased to sub~1nm. Under such low spacing, accurate spacing control becomes more important for mitigating the risk of head-disk interference and getting good bit per inch (BPI) performance. Dual-heater slider technology has been considered as a most useful solution. This paper introduces the advantages of dual heater in reading/writing mode. To utilize these advantages, precise spacing control with good touchdown detectability is necessary. Therefore, the touchdown detectability of dual-heater slider was investigated using three TD detection methods under writing and reading mode. Result shows that a single method is difficult to get the best TD detectability under both writing and reading mode. Hybrid method may be a feasible solution. © (2013) Trans Tech Publications, Switzerland.
