Remanent state noise in particulate magnetic recording media
… is the variation in stray flux emanating from a magnetic recording medium which is in a remanent state of magnetisation. A portion of this noise is related to the magnetic microstructure of the recording medium. This study had two main objectives. The first was to devise and implement hard and …

An investigation of thin film magnetic recording media
… surface of commercial thin film metal evaporated magnetic recording media have been correlated to recording error and signal degradation measurements. Modified and adapted commercial Hi-8 video recorders have been used for sample generation whilst analytical techniques such as SXPS,IMS and SEM …

High Anisotropy CoPt (L1(0) & L1(1) Phase) Magnetic Recording Media Films
For magnetic recording technology, much effort is currently devoted to the achievement of areal density up to 1 Tb per square inch and beyond. The enhancement of the magnetic recording areal density is governed by the characteristics of magnetic recording media. Media material with large …

Fabrication and application of patterned magnetic media
… to overcome the superparamagnetism in thin film magnetic recording media, a novel magnetic medium, called patterned medium, is studied here as a potential candidate for the future hard disk storage application. Within the patterned medium, one bit is stored in one magnetic unit, which has to be …

TRANSVERSE SUSCEPTIBILITY STUDIES OF RECORDING MEDIA
… has been developed for the investigation of magnetic recording media. The susceptometer was based on the design of Pareti and Turilli[4] with modifications to the solenoid and sensing coils. The modifications have resulted in an improvement in the signal to baseline ratio of a factor of 525, …

Particulate dispersions for magnetic recording data
The study of a magnetic recording media dispersion has been carried out using hindered settling analysis, the purpose of which was to probe the equilibrium state structure in zero applied magnetic field. The system chosen for the main study was based on a commercial formulation of a y-Fe 203 …

Quantitative High-angle Annular Dark Field Scanning Transmission To Electron Microscopy For Materials Science
… reported by other workers. The L10 class of hard magnetic materials has attracted continuous attention as a candidate for high-density magnetic recording media, as this phase is known to have large magnetocrystalline anisotropy, with magnetocrystalline anisotropy constant, Ku, strongly dependent …

Computer stimulations of particulate recording media
In order to further understand the behaviour of magnetic recording media the relationship between the microscopic and the macroscopic behaviour must be more precisely understood. Computer simulations are an invaluable tool in the development and testing of models of these media. Presented here are …

Micromagnetic analysis of co-based magnetic nanostructures.
Micromagnetic analysis was employed in order predict the dynamical behavior of a variety of magnetic structures utilized in information storage devices. First, the surprising behavior of homogeneous perpendicular recording media was micromagnetically investigated. It is common to model recording …

Syntheses, properties, and reactions of transition metal complexes of di(tert-butyl)amide and 2,2,6,6-tetramethylpiperidide
… and potential applications in tool coatings and magnetic recording media. In order to develop new chemical vapor deposition (CVD) precursors for these late transition metal nitrides, we have explored the synthesis, characterization, and CVD of late transition metal complexes of the sterically …
