The areal (surface area density of bits) storage magnetic hard disks is continually increasing, with typical available commercial densities being around 10Gbits/in 2 . It predicted that in excess 40Gbits/in will be possible before the year 2003. A number key issues arise from this development, such as need to determine and control accurately dynamic flying height ( z ‐axis) read‐write head, which affected by apparent distortion disk surface due rotation‐induced resonance. As a result...

A scanning laser microscope has been designed to observe the dynamic behaviour of domain switching during thermo-magnetic write process and subsequent magnetisation state (domain orientation) in thin-films devices. It will also be used magneto-optic (MO) disk material thermo-magnetically prior imaging. Images are derived from longitudinal polar Kerr effects, which wavelength dependent, using appropriate wavelength. In this paper different configurations for imaging described, some initial...
