Abstract: A method and apparatus for format patterning magnetic recording media with servo-control patterns is disclosed herein. The method comprises the steps of applying the control pattern using a resist in liquid form onto the media material by conventional applying techniques. A layer of a thin metallic film is then deposited over the resist and uncovered substrate areas. The resist and its overlayered metal is then removed using a liftoff technique by dissolving the resist in its particular solvent. A control pattern of deposited metallic film remains in those non-resist areas. In the alternative, the process can also use an etching bath to create the servo control pattern.

Abstract: A computer-controlled-manipulator gripper with a set of three-degree-of-freedom force sensors on each finger having strain gauges and 90 DEG shift in orientation of the sensors includes an asymmetric, offset relationship of the location and orientation of analogous sensors on the two fingers in order to obtain different measurements from the two fingers.

Abstract: A six degree of freedom force transducer is provided on a manipulator's hand and includes a plurality of I-beam modules having strain gauges on the flat surfaces of the thin legs of each I-beam for measuring the bending moments of each leg. According to one embodiment, a pair of strain gauges are located on each side of the leg, providing a total of four gauges in each leg. The end bells of each I-beam are adapted to be rigidly interconnected with either other I-beams, structural members of the manipulator fingers, the drive member for the manipulator, or to intermediate coupling blocks designed to rigidly interconnect I-beams. A plurality of I-beams and interconnecting blocks can be connected in various configurations to provide a determination by the strain gauges of the six components of forces and moments which are applied by forces and moments on the fingers of the manipulator system. The I-beams and interconnecting blocks are arranged in x-y-z orthogonal directions such that the structural stiffness is in the same order in different directions. The moment at each basic module can be measured by the voltage output of a bridge associated with the strain gauges. In this fashion, a determination of the position and orientation of an object in the manipulator's hand can be readily provided by a computer which solves the force and moment equilibrium equations associated with the I-beam strain gauges.
