Method for linearizing microactuator hysteresis for a disc drive |
摘要 |
Linearizing hysteresis of a microactuator for a disc drive by modeling the microactuator with a first polynomial equation to provide a linear displacement response of the microactuator responding to an applied voltage, deriving a set of constants from a plurality of burst patterns for use with the first polynomial equation to provide a set of variables for use in resolving the second polynomial equation to provide a set of equations from which a set of constants can be derived for use by the second polynomial equation to provide a voltage to the microactuator to displace the microactuator by a predetermined incremental distance.
