Effects of the Mass and Load Force of a Spherical Contact Slider on Wear and Jumping Characteristics

Abstract

The authors investigated the effects of the slider mass and load force on both the jumping height and the wear of the contact pad for contact recording, using simulation and vibration energy experiments. The wear characteristics were determined by comparing the simulation results with those of the acoustic emission experiment, using a spherical contact pad with Hertz's contact. It was found that a low load leads to low wear on the contact pad. A high-mass slider, with a conventional magnetic head, can be used for contact recording. The use of liquid bearings with thick lubricant is an effective method for reducing highfrequency slider vibration.
