Magneto-Thermo-Elastic Stresses and Perturbation of the Magnetic Field Vector in an EGM Rotating Disk

In this article, the magneto-thermo-elastic problem of exponentially graded material (EGM) hollow rotating disk placed in uniform magnetic and temperature fields is considered. Exact solutions for stresses and perturbations of the magnetic field vector in EGM hollow rotating disk are determined using the infinitesimal theory of magneto-thermo-elasticity under plane stress. The material properti...

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...

Beam Deflectors for Magneto-Optical Recording Heads

Nonmechanical beam deflectors, particularly acousto-optical and electro-optical deflectors, are being considered for the access and tracking functions of a magneto-optic recording head. In this report, the suitability of electro-optic deflectors for these functions is explored. For applications requiring modest deflection, electro.optic deflectors require less power and exhibit higher optical t...

Magneto-optical micromechanical systems for magnetic field mapping

A new method for magnetic field mapping based on the optical response of organized dense arrays of flexible magnetic cantilevers is explored. When subjected to the stray field of a magnetized material, the mobile parts of the cantilevers deviate from their initial positions, which locally changes the light reflectivity on the magneto-optical surface, thus allowing to visualize the field lines. ...
