Shuyu Zhang, Auteur ; Sung-Chang Lee, Auteur ; Dongman Kim, Auteur |Thermomechanical actuation (TMA) at the transducer region of the air bearing surface (ABS) protrudes from the transducer toward the recording media. This actuation induces a change in the air bearing pressure and a concomitant lift of the slider[...]

Raja R. Katta, Auteur ; Andreas A. Polycarpou, Auteur ; Sung-Chang Lee, Auteur |Scratch-related magnetic signal degradation can occur during magnetic storage hard disk drive operations when the read-write heads contact the spinning multilayer disks. To investigate this phenomenon, controlled nanoscratch experiments were per[...]

Sung-Chang Lee, Auteur ; George W. Tyndall, Auteur ; Mike Suk, Auteur |Flying clearance distribution with thermal flying height control (or thermomechanical actuation) is characterized. Especially, factors contributing to variation in the flying clearance are identified based on the flying height change profiles ta[...]

Shuyu Zhang, Auteur ; Brian Strom, Auteur ; Sung-Chang Lee, Auteur |For a hard disk drive operating in a humid environment, the water vapor in the slider’s air bearing is typically compressed beyond its saturation vapor pressure, causing the vapor to condense. Consequently, the air bearing pressure decreases and[...]
