Abstract
A magnetic head slider in a magnetic disc drive system has a contact pad on a liquid bearing surface of the slider which bears on liquid applied on the magnetic disc. Each molecule of the liquid has at least two-polar groups for bridging the contact pad and the magnetic disc by intermolecular force. The bridging prevents the magnetic head slider from jumping over the magnetic disc.
