Abstract
A channel senses head-to-disc contact vibrations in a vibrational noise spectrum produced in a mass storage device. The channel includes a suspension system with a suspension modal resonance. The channel includes a vibration sensor that senses head-to-disc contact vibrations through the suspension system. The vibration sensor has a sensor modal resonance that overlaps the suspension modal resonance.
