Patent ID: 8599506

Claim:
A hard disk drive (HDD) comprising: a slider, wherein said slider comprises a resistive temperature detector (RTD) configured to detect a temperature generated by one or more of slider spacing and contact with a media of said HDD; a slider signal controller configured to control bias signal of a slider with respect to a media potential; a real-time media-disk fly-height and contact detector configured to detect one or more of temperature generated by real-time media-disk slider spacing and real-time media-disk contact; and a real-time relative fly-height determiner configured to detect real-time relative fly-height of said slider based on analysis of a modulated portion of a high-frequency signal coupled to an element of said slider, wherein said slider signal controller, said real-time media-disk fly-height and contact detector, and said real-time relative fly-height determiner are included in a read/write Integrated Circuit (IC) of said HDD.
