摘要： Air bearing sliders that achieve fly height profiles which allow improved areal density and file capacity. The sliders include angled features in such a way that they align with the air skew at textured zones on a disk. The angled features are selected to create a first air pressure distribution at first predetermined radii of the recording medium and a second air pressure distribution at second predetermined radii of the recording medium. The spacing profile may be obtained by skewing the whole or a portion of one or more rails with respect to the air bearing slider edges. In designs with a center rail, the spacing profile may be customized by skewing the center rail. Further optimization may be provided by altering the taper of the rail widths. Still further, the entire slider can be mounted with a skew with respect to the suspension to achieve the required fly height profile variations rather than skewing one or more of the rails. The exact shape of the profiles are optimized to the file's magnetic and mechanical needs and improve capacity and density in files that have constant texture (or no texture) throughout the whole disk surface.

摘要： A tool holder constituting an adaptive machining control system to automatically manipulate tool rake angle using in-process force feedback. The tool holder includes a rotatable member for holding a cutting member which cuts a workpiece, a motor to rotate the holding member, and a sensor and control logic to sense cutting forces and activate the motor to rotate the holding member and change the tool rake angle. The cutting member is held so that it rotates about an axis through its cutting tip to change the rake angle without varying the depth of cut on the workpiece. In an alternative embodiment, a manually operated tool holder is manipulated to similarly rotate a cutting member to vary the rake angle.
