摘要： One surface of a piezoelectric actuator is bonded to a suspension via bonding agents. The piezoelectric actuator is bonded to the suspension at two positions sandwiching a coupling portion therebetween. Namely, the bonding is performed at respective one end portions of two piezoelectric active portions, and these end portions are situated on opposite sides with respect to the coupling portion. In the bonding, since the two piezoelectric active portions are integrated via the coupling portion, relative position adjustment between the piezoelectric active portions is very easy. Further, the number of terminals to connect with a wiring pattern formed on the suspension is only two, and the suspension need not be rotated 180 degrees at the time of bonding, so that the time required for bonding is short.

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.

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.
