To realize higher areal densities towards 10 Tbit/in2, the ever decreasing flying height of the slider approaches the near-contact regime. It is essential to monitor head-disk interactions to prevent instability and damage to the head-disk interface. In this study, a piezoelectric sensor array embed...
