Method to convert and calibrate the embedded contact sensor signal to clearance and spacing information using interface voltage control

Embodiments of the present invention generally relate to a method for obtaining head/disk clearance based on ECS signal. The ECS is calibrated by applying different interface voltages to cause changes in the head/disk clearance, the ECS signal at each interface voltage is obtained, and the relations...

description Embodiments of the present invention generally relate to a method for obtaining head/disk clearance based on ECS signal. The ECS is calibrated by applying different interface voltages to cause changes in the head/disk clearance, the ECS signal at each interface voltage is obtained, and the relationship between the change in head/disk clearance and the ECS signal is calculated. From this relationship, the head/disk clearance may be obtained based on ECS signal.
