1. one kind is used for controlling the method that an electro-optical system is carried out data access, comprises:

  • When the read head of an electro-optical system along a first direction slide and the motor rotary speed of this electro-optical system when changing, judge that whether difference value between this motor rotary speed and a preset rotation speed is greater than a tolerance value;

    If this difference value greater than this tolerance value, then makes this read head reply distance towards the reverse direction slip one of this first direction;

    AndRepeat to make this read head along this first direction slide, judge between this motor rotary speed and this preset rotation speed difference value and in this difference value during still greater than this tolerance value, make the step of this read head again, till this difference value is less than this tolerance value towards the reverse direction slip of this first direction.
