The galvanometer scanner is a type of swaying motor used in laser-drilling machines that is able to position the laser at more than 2,000 points per second. In recent years, the number of holes in printed circuit boards for mobile phones and other el

Under recent low flying height conditions of magnetic head sliders, both the heat generated by the high-frequency current in the write coils and the rise in the ambient temperature cause local protrusion on head elements. Such protrusion reduces the

Unsteady airflow in an actual hard disk drive (HDD) which has a rotary actuator is numerically simulated by using the large eddy simulation technique, and the aerodynamic force affecting head gimbal assembly (HGA) is estimated from the simulation. Th

The behavior of the air flow inside a hard disk drive is evaluated by a three-dimensional unsteady-flow analysis technique called large eddy simulation (LES). The simulation shows that the fluctuation of the aerodynamic force is strongly correlated w

As one of the important aerodynamic problems of magnetic disk drives for microcomputers, a flow between shrouded corotating disks and its instability have been investigated. The four-decker circular disk pack is enclosed in a cylindrical container to

We studied a magnetic recording head of a three-pad-slider which had flat-inclined air-bearing surfaces. We expected a small friction force and a small velocity dependence on the flying height from the configuration. We confirmed these expectations b

We studied a magnetic recording head of a three-pad step-slider with a stepped air bearing surface (ABS). The contact force of the three-pad step-slider of positive pressure is smaller than that of conventinal negative pressure sliders when it contac

Both the heat generated by the current in the write coil and the rise in the surrounding temperature cause local thermal protrusion (TPR) on magnetic-head elements. Such protrusion reduces the flying height of the head slider below the design value,
