PARTICULATE FILMS FOR MAGNETO·OPTICAL RECORDING I. THEORY OF THE MAGNETO·OPTICAL EFFECT M. ABE and M. GOMI

چکیده
For magneto-optical(MO) recording media we propose particulate films with magnetic fine particles dispersed in binders. Using effective dielectric tensor Faraday rotation ~ and absorption coefficient -a-are calculated for the particulate films containing Bi-substituted YIG and Co fine particles. The MO figure of merit O'~ of the particulate films exceeds that of continuous magnetic films. This enhancement is prominent for Co (or metal in general) compared to Bi-YIG (or oxide in general).

DENSITY MAGNETO·OPTICAL DISK RECORDING USING MAGNETIC FIELD MODULATION WITH A CAPACITY OF 650 MB/064 mm
We have investigated high-density magneto-optical recording on a conventionally structured disk with a diameter of 64 millimeters using magnetic field modulation to achieve a capacity of 650 Mbytes. With the groove conditions optimized, the jitter with cross-talk from adjacent tracks was 7.2% and the recording power margin including overwriting and crosswriting was ±20%. As a result of minimizi...
متن کاملEffect of ventilation air velocities on diesel particulate matter dispersion in underground coal mines
This paper presents a detailed account of computational fluid dynamics (CFD) simulations undertaken to investigate the influence of intake (ventilation) air velocities on the flow patterns of diesel particulate matter (DPM) generated by a man-riding vehicle operating in a straight rectangular cross section tunnel in an underground coal mine. The simulation results are validated against an earli...
متن کاملInvestigation of extinction spectra of THTS Mn thin films and comparsion with discrete dipole approximation simulation results
In this work, the extinction spectra of the nano-structure of the Tilt Helical and Stair-like Towers of Mn thin films were obtained using discrete dipole approximation (DDA) simulation for both s-and p-polarization at two incident light angles of 10°, and 60° at different azimuthal angles for the there samples with different tilt. Obtained results are compared with the experimental optical exti...

متن کاملInvestigation of structural and electronic properties of small Au n Cu m (n+m≤5) nano-clusters for Oxygen adsorption
In this study, the structures, the IR spectroscopy, and the electronic properties of AunCum (n+m≤5) bimetallic clusters were studied and compared with those of pure gold and copper clusters using the generalized gradient approximation (GGA) and exchange correlation density functional theory (DFT). The study of an O2-AunCum system is important to identify the promotion effects of each of the two...
