Control method of dynamically correcting stabilized error of a spindle motor in an optic storage device

Abstract

A control method for dynamically correcting stabilized error of a spindle motor in an optic storage device. The control method comprises the steps of: (a) At first, under the condition that the spindle motor is stable, checking a rotary speed of the spindle motor so that an initial constant offset value is acquired according to said rotary speed, (b) Reading the stabilized error of the system and determining whether the constant offset value should be corrected, (c) Then, using a control mode of section dividing and staged value to modify the constant offset value, and (d) Suppressing the stabilized error to a minimum value.
