The head-disk interface (HDI) in heat-assisted magnetic recording (HAMR) hard disk drives
is a system where a laser beam is launched from a recording head and focused on a …

Laser-lubricant interaction has been a critical reliability issue in a thermo-tribological system
named heat-assisted magnetic recording, one of the next generation hard disk drive …

In heat-assisted magnetic recording (HAMR), a laser is employed above the read-write
transducer to provide energy to the media, lowering its coercivity. However, the laser also …

In hard disk drives, a recording head and a recording disk constitute a high-speed sliding
system: head–disk interface, where the head with a prescribed thermal protrusion on its …

This report evaluates the applicability of the ideal gas law in the pressurized air-bearing of
hard disk drives when calculating the relative humidity. We employ a semi-analytical …

Ever since the first hard disk drive (HDD) was invented in 1956, it has played a dominant
role in global data storage needs. Conventional HDDs, however, have reached the …
