Corrosion Mechanisms in Magnetic Recording Media
29 Jul 2013 | Contributor(s):: Brian Demczyk
This presentation describes the corrosion process in longitudinal and perpendicular recording media, based upon electron and scanning probe microscopic analysis.
Atomic Force Microscope Investigations of Lubrication Layers
26 Nov 2012 | | Contributor(s):: Brian Demczyk
This presentation discusses the characterization of hard disk lubrication layers by phase contrast atomic force microscopy.
On the Origin of the Orientation Ratio in Sputtered Longitudinal Media
26 Oct 2012 | | Contributor(s):: Brian Demczyk
This presentation discusses the influence of processing on the development of nanostructural features and their relationship to the orientation ratio, which is of importance in determining magnetic properties in longitudinal recording media. fabricated hard disks were characterized by...
Nanoscale Dimensions in Hard Disk Media
27 Sep 2012 | | Contributor(s):: Brian Demczyk
This presentation examines the relationship of longidudinal hard disk media nanostructure,lubricant distribution and surface nanoroughness to disk contact to flying time transition and lubricant thickness to data zone takeoff. Also included is a model of disk wear.
