ABSTRACT:
An arrangement and corresponding method for external shock protection for a storage device in which the movement of the slider in relation to the disk is prevented by applying an electrostatic attractive voltage between the slider and disk responsive to a shock event. The electrostatic attractive force generated acts to hold the slider down to reduce erratic movement and possible resulting damage. The shock protection system can be implemented in the operational mode of the drive when the slider is flying and/or when the slider is parked on the disk.
