To understand the cause of read/write error due to lube accumulation, a model to simulate the slider’s response to “soft contact”, which can occur between a lubricant droplet on the disk and a slider, was developed. The contact impact model is based on the water-hammer pressure model with an additional damping force, where the wave-shock pressure is assumed to function as the soft contact pressure, and the damping force defines the damping characteristics of the impact which are due to the lubricant’s high viscosity. This modeling and simulation are helpful to us in understanding the read/write signal loss due to a lube droplet at head disk interface.
