To further increase the areal storage density of hard disk drive, one solution is to reduce the
spacing between the magnetic head and disk to sub-1-nm regime. Such ultra-low spacing …

We utilize thermal fly-height control (TFC) technology to perform in situ measurements of
carbon overcoat wear at the angstrom level at the read–write area of magnetic recording …

In this study, the wear properties of a magnetic head slider on disks lubricated by ultra-thin
perfluoropolyether (PFPE) lubricants with different molecular weights were evaluated by the …

The understanding of tribo-and electro-chemical phenomenons on the molecular level at a
sliding interface is a field of growing interest. Fundamental chemical and physical insights of …

Understanding the dynamics and instability of a thermal fly-height control (TFC) head slider
close to and at touchdown (TD) on a magnetic recording disk is essential for developing a …

The evaluation of submonolayer lubricant mobility is becoming important in the field of
nanotribology, in particular, in hard disk drives for realizing the near-contact or surfing …

To reveal the mechanism of head-disk interface wear behaviors, this paper proposed a
novel transformation on slider's vibration signals, which was derived to having a strong …

Reducing the fly-height between the head and disk to less than 1 nm with high reliability is
necessary to improve the recording density of magnetic disks. Therefore, the mechanism of …

Thermal flying-height control (TFC) technology has been used in the last few years in hard
disk drives (HDDs) to achieve a lower flying height for higher storage areal density. In this …

Transient characteristic of heat exchange between closely positioned bodies has become
an important issue owing to the continuous miniaturization of many technologies such as …
