摘要： A magnetic head assembly includes: a slider; an actuator disposed on an end face of the slider; and a magnetic head unit connected to the actuator. The actuator has a structure in which multiple electrodes are arranged in a piezoelectric body, and is driven in d33 mode. In other words, when a predetermined voltage is applied to the actuator, a portion between the electrodes in the piezoelectric body expands or contracts with respect to a voltage application direction. When the piezoelectric body of the actuator expands or contracts, the magnetic head unit is deformed, and the deformation causes a change of the distance between a magnetic head (recording element and reproducing element) and a magnetic recording medium.

摘要： A coating film is formed on the whole surface area of a body part. Formation of the coating film may be done by immersing the body part in a solution of parfluoropolyether. Then, the parfluoropolyether constituting the coating film is joined with the side surfaces of the body part by irradiating Xenon excimer laser in a nitrogen atmosphere onto the side faces of the body part, or to the surface exposing an electrode layer. As a result, the protective film is formed only on the side surfaces of the body part. Thus, the protective film is formed as a monomolecular film. Total body part is then cleaned by 2,3-dihydrodecafluoropentane to remove non-reacted coating film, thereby completing a multi-layer piezoelectric element.
