This invention relates to a slow pull dryer comprising a rectangular water tank and a wave eliminator. The water tank has four vertical side-walls and a bottom plate with a water hole for filling hot water wherein the hot water filled in the water tank can spill out of the water tank from the top side of one predetermined side-wall. The wave eliminator is installed at the bottom of the water tank. The lower side of the wave eliminator has a rectangular recess facing downward, and the upper side of the wave eliminator has a line-shaped opening in parallel with the predetermined side-wall. The hot water from the water hole flows into the recess and its flowing speed is slowed down in the recess. The line-shaped opening allows the hot water in the recess flow upward into the upper portion of the water tank and form a panel-shaped vertical water flow. When the vertical water flow reaches the surface of the hot water in the water tank, it will form a horizontal water flow moving toward the to side of the predetermined side wall. Particles and dusts drifting on the surface of the hot water can be carried out of the water tank by the horizontal water flow.

A glide head with mounted PZT sensor is used to obtain a glide avalanche curve. The glide head is subsequently gradually decreased until the signal is extremely high. First, at least one resonance frequency of the glide head is determined. The frequency component of the PZT glide signal to each specific irregular peak is analyzed by using the speed of the glide head divided by the bump spacing, multiplied by a factor, m, where m is an integer number. The next step of the present invention is to determine a glide avalanche break point of the recording medium. Then, the glide avalanche point is determined in the region which is between the irregular peaks and the extremely high signal.
