This paper studies of the pitch static torque of the suspension on the multiple flying states of two types of the negative pressure slider by simulation. It is revealed that the sliders may have one to three balanced flying states under certain conditions. Only one of the states is lower enough for normal read/write operations. The relationship between the multiple flying states and the pitch static torque is presented, and the methods to avoid of the higher flying states are discussed. A special method to search for the multiple flying states is introduced.
