Abstract

This method is capable of evaluating thermal erasure properties of disks and head sliders for both longitudinal and perpendicular magnetic recording. It also enables us to study the details of head disk interaction, such as slider disk contact points and slider vibration modes responsible for the thermal erasure. This is difficulty to be obtained by other means.
