An Active Flying Slider for Magneto-Optic Disk Focusing
Low mass flying heads for magneto-optic recording would yield fast access times. A design concept for such a head was proposed and computer modeling of its flying characteristics were conducted. Calculations indicated that the head (slider) will follow low frequency undulations the disk (resulting from disk run-out and disk warp) to within one depth of focus of the read/write beam. Thus the ill...
متن کاملOptical profiling using white light interference in spectral domain
The rapidly developing fields of Micro-Electro Mechanical System (MEMS) and micro optics require non contact and high precision measurements. Optical profilers are ideally suited for this. Monochromatic Phase Shifting Interferometry(PSI) can be used to measure slowly varying profiles and step height of less than half a wavelength. White light interferometry is used when large step height are to...
متن کاملDesign and Dynamics of Flying Height Control Slider With Piezoelectric Nanoactuator in Hard Disk Drives
To achieve the areal density goal in hard disk drives of 1 Tbit/ in.2 the minimum physical spacing or flying height (FH) between the read/write element and disk must be reduced to 2 nm. A brief review of several FH adjustment schemes is first presented and discussed. Previous research showed that the actuation efficiency (defined as the ratio of the FH reduction to the stroke) was low due to th...
متن کاملLateral interference, spacing, and word legibility
Visual processing of individual characters within a word can interfere with one another thereby decreasing word legibility. This largely results from the lateral interference occurring in the retina and the primary visual cortex, with the distance over which it operates largely fixed in size. Analysis of previous data demonstrates that the default spacing for 10 and 12 pt font is just large eno...
متن کاملExperimental study of slider dynamics induced by contacts with disk asperities
Vertical vibrations at the slider leading edge exited by a disk asperity were investigated in a drive level system, using laser Doppler vibrometry and acoustic emission (AE) sensors. The flying height change at the leading edge of a thermal flying-height control slider was measured for different power inputs to the heater element. The maximum spacing change at the slider leading edge was found ...
