Numerical simulation of shock response of disk-suspension-slider air bearing systems in hard disk drives
As non-traditional applications of hard disk drives emerge, their mechanical robustness during the operating state is of greater concern. A procedure for simulating the shock responses of a disk-suspension-sl...

Use of an upwind finite volume method to solve the air bearing problem of hard disk drives
In this paper we present an upwind higher order finite volume numerical scheme over unstructured triangular mesh to solve the slider air bearing problem of hard disk drives. The scheme is nodal based, which u...

Nano-Hardness, Nano-Friction and Nano-Wear of Ultra-Thin Overcoats
Thin film magnetic disks require protective overcoats, usually some form of carbon, to guard against corrosion and wear from interaction with the read/write transducer. In current products these films are less...

A pretreatment process for enhanced diamond nucleation on smooth silicon substrates coated with hard carbon films
Diamond nucleation on unscratched silicon substrates coated with thin films of hard carbon was investigated experimentally with a microwave plasma-assisted chemical vapor deposition system. A new pretreatment ...

Chemical structure and physical properties of diamond-like amorphous carbon films prepared by magnetron sputtering
Thin films of amorphous carbon (–C) and amorphous hydrogenated carbon (a–C: H) were prepared using magnetron sputtering of a graphite target. The chemical structures of the films were characterized using electron...

Power Density Effects in the Physical and Chemical Properties of Sputiered Diamond-Like Carbon thin Films
Thin films of diamond-like amorphous carbon were prepared by dc magnetron sputtering. A systematic variation in the physical properties of the films (mass density and electrical resistivity) was found as a fun...

On Nonspecular Reflection of Bounded Beams for Layered Half Spaces Under Water
We study the recently derived reflection coefficient for plane waves in a liquid that are incident on the liquid-solid interface of a solid half space which consists of a single layer of one elastic material b...

Plane steady vibration of an elastic wedge
The problem of plane steady vibration of an elastic wedge of arbitrary angle (less than 180 degrees) subject to harmonic normal and shearing tractions on its faces is reduced to a system of singular integral e...

Plane steady vibration of an orthogonal elastic wedge
The problem is reduced to a single Fredholm integral equation by using a superposition of two half-plane solutions. The treatment is exact within the theory of linear elastodynamics. Dissipation is introduced ...
