摘要： A unit 101 calculates a plurality of sets of objective functions of sample sets of input parameters. A unit 102 approximates the objective functions using a polynomial on the basis of the calculation result of the unit 101. A unit 103 calculates a logical expression indicating a logical relation between arbitrary two or three objective functions, of the plurality of mathematically approximated objective functions as an inter-objective function logical expression by a QE method. A unit 104 displays areas that the values of the objective functions can take as usable areas according to the inter-objective function logical expression. Units 105 and 106 determine an optimum set of design parameters by limiting the sets of design parameters to corresponding sets of design parameters in the neighborhood of a Pareto boundary on the basis of the Pareto boundary of an objective function recognized from the usable areas displayed.

摘要： A logical expression indicating a logical relation between arbitrary two or three objective functions, of a plurality of mathematically approximated objective functions is computed. A feasible region/sensitivity information display unit displays the feasible region in arbitrary objective space according to it. An inverse image computation unit computes a point or area in design space corresponding to arbitrary design parameters in relation to a point or area specified by a user in the feasible region of the objective space. A feasible region/sensitivity information display unit displays the distribution state of the corresponding point or area as sensitivity information in relation to the specified point or area in the feasible region.

摘要： A scanner scans the scan subject by means of utilizing a rotative movement of a rotatable movable member for rotatably moving on a predetermined rotation axis. A scan mirror is supported by a single support axis. A rotary power of drive motors is converted into a reciprocating motion by crank mechanisms to rotatively move the scan mirror. A rotary angle of the scan mirror is detected by utilizing a principle of an interferometer.

摘要： A head arm includes a main body, partially located with a first area above a recordable medium. The main body includes a first surface opposite to the recordable medium and a second surface opposite to the first surface. A hole extends through the main body between the first and second surfaces. The main body also has a first connector portion connectible to a driving portion; and a second connector portion connectible to a head. The through hole is formed on only one side with respect to a line that halves the first area between said first and second connector portions.

摘要： Lubricant on a rotating recording medium can attach to a slider, particularly on the pad formed in the proximity of the trailing edge. In the slider of this invention, lubricant is not accumulated in the vicinity of the trailing edge and can be drawn to the trailing edge and dispersed constantly. The head slider includes a center pad formed on an air bearing surface in the vicinity of the center of a trailing edge of the slider. A trailing pad is formed so as to bridge a trailing edge of the center pad and the trailing edge of the slider. The trailing pad is formed lower than a highest surface of the center pad and higher than a lowest surface of the slider.
