Abstract
An apparatus and associated method for observing an analog position signal of a control object in relation to positional indicia, recalling a previously stored runout correction value associated with the positional indicia, and calculating a corrected position signal for the control object in relation to the position signal and the runout correction value.
Claims20
A method comprising observing an analog position signal of a control object in relation to positional indicia, recalling a previously stored runout correction value associated with the positional indicia, and calculating a corrected position signal for the control object in relation to a nonlinear combination of the position signal and the runout correction value.
An apparatus comprising:
- a control object;
- and
- a servo circuit configured to position the control object in response to a corrected position signal that is generated in relation to a nonlinear combination of an analog position signal of the control object in relation to positional indicia and a runout correction value associated with the positional indicia.
An apparatus comprising:
- a control object;
- and
- means for positioning the control object in response to a nonlinear combination of an observed position of the control object with respect to positional indicia and a previously stored runout correction value associated with the positional indicia.
