    Abstract: The microactuator (30) comprises a motor element (32) including a stator (38) and a rotor (40) capacitively coupled to the stator (38); an actuator element (34) having a circular structure; and a transmission structure (36) interposed between the motor element (32) and the actuator element (34) to transmit a rotary movement of the motor element (32) into a corresponding rotary movement of the actuator element (34). In particular, the transmission structure (36) comprises a pair of transmission arms (80, 81) identical to each other, arranged symmetrically with respect to a symmetry axis (A) of the microactuator (30). The transmission arms (80, 81) extend between two approximately diametrically opposed regions of the rotor (40) to diametrically opposed regions (84) of the actuator element (34).

    Abstract: The microactuator (9) is attached to a first face (43) of a coupling (8) formed on a suspension (5), so that the R/W transducer (6) projects from the opposite face (44). A hole (41; 56) in the coupling (8) permits passage of an adhesive mass (42) interposed between the rotor (11) of the microactuator (9) and the R/W transducer (6). A strip (40) of adhesive material extends between the die (25) accommodating the microactuator (9) and the coupling (8), and externally surrounds the microactuator (9). The coupling (8) acts as a protective shield for the microactuator (9), both mechanically and electrically; it covers the microactuator (9) at the front, and prevents foreign particles from blocking the microactuator (9); in addition it electrically insulates the R/W transducer (6), sensitive to magnetic fields, from regions of the microactuator biased to a high voltage. With the gimbal (8), the strip (40) forms a sealing structure, which in practice surrounds the microactuator (9) on all sides.

    Abstract: Described herein is a read/write transducer for a hard disk drivewith dual actuation stage, comprising at least one hard disk and at least one suspension carrying the read/write transducer. The read/write transducer comprises a supporting body having a substantially parallelepipedal shape, a read/write head arranged on a front face of the supporting body, and a grating defined on one of the side faces of the supporting body during the process of manufacture of the read/write transducer. The grating enables measurement of the position of the read/write transducer with respect to the corresponding suspension in an optical way using a laser transmitter emitting and directing towards the grating a laser beam, and a laser receiver arranged to intercept the laser beam reflected by the grating and outputting a position signal on the basis of which it is possible to calculate, in a simple way, the position of the read/write transducer with respect to the corresponding suspension.

    Abstract: A microelectromechanical structure (40) includes a rotor element (22) having a barycentric axis (G) and suspended regions (25) arranged a distance with respect to the barycentric axis. The rotor element (22) is supported and biased via a suspension structure (30, 45, 49) having a single anchoring portion (49) extending along the barycentric axis (G). The single anchoring portion (49; 73; 92) is integral with a body (41) of semiconductor material on which electric connections (50a) are formed.
