ABSTRACT:
A magnetic head assembly within a transducer is caused to float over the recording surface of a medium during operation while being in contact with the surface in the non-operational state. The transducer is supported by a load beam via a flexible member which deforms under the influence of frictional force between the transducer and the surface during landings and take-off. The load beam has integral stop plates which abut against a part of the transducer to regulate the deformation of the flexible member so that it stays within a predetermined range in the event of any relatively high frictional force being applied to the transducer.
