Abstract: A suspension includes a load beam, a flexure and a dimple portion. The flexure includes a tongue. The dimple portion swingably supports the tongue at least over a first position and a second position. In the tongue, first pillow portions supporting a slider and an adhesive portion fixing the slider are provided. In the load beam, a second pillow portion protruding towards the slider is provided. The second pillow portion is in contact with the slider when the tongue is located at the first position, and separates from the slider when the tongue has moved to the second position.

Abstract: A piezoelectric element easily and surely forms polymer coatings on peripheral end faces of the piezoelectric element without deteriorating a yield of the piezoelectric element. The piezoelectric element is manufactured by a method including steps of cutting a piezoelectric element out from a base piezoelectric material plate so that peripheral end faces are formed to define a peripheral shape of the piezoelectric element, and forming polymer coatings on at least objective areas of the peripheral end faces of the piezoelectric element by vapor deposition polymerization.
