摘要： A head assembly includes a suspension having a gimbal, a flexible printed wiring sheet having a plurality of conductor patterns and adhered to the suspension, first and second piezoelectric actuators mounted on the gimbal, and a head slider mounted on the first and second piezoelectric actuators. The first and second piezoelectric actuators are adhered to the gimbal at end portion adhesion portions symmetrical with respect to the center of pivotal motion thereof and are adhered to the head slider at end portion adhesion portions on the opposite side disposed symmetrically with respect to the center of pivotal motion similarly. Consequently, when a voltage is applied to the first and second piezoelectric actuators through the flexible printed wiring sheet, a couple of forces can be generated which vary the posture of the head slider only in one direction around the center of pivotal motion.

摘要： A magnetic head positioning mechanism is provided which is excellent in shock-resistance and can achieve high positioning accuracy. By constructing the magnetic head positioning mechanism so that a fine actuator section is composed of an actuator spring made from a thin steel plate, a base plate made from a thick steel plate to be Functioned to the actuator spring, stiffness of the fine actuator section in a vertical direction can be improved with flexibility of a driving spring section mounted on the actuator spring being still kept, that is, with sufficient positioning accuracy and satisfactory stroke being maintained. Moreover, by designing a strength of the fine actuator section so that the actuator spring and a holder arm do not overlap when the base plate is connected to the holder arm, the fine actuator section can be made thin and implementing of the fine actuator section among narrow plates in a positioning device is made easy.

摘要： A micro-actuator for a head gimbal assembly includes a support structure and a PZT element. The support structure includes a bottom support integrated with a suspension flexure of the head gimbal assembly, a top support adapted to support a slider of the head gimbal assembly, and a leading beam that couples the bottom support and the top support. The leading beam includes a weak point that allows the top support to rotate about a rotational axis in use. The PZT element is mounted between the top and bottom supports. The PZT element is excitable to cause selective rotational movement of the top support about the rotational axis in use.

摘要： Apparatus and method for selectively applying a voltage to one major surface of a pair of piezoelectric motors (PZTs) on a disk drive head suspension with a primary plane of a load beam of the head suspension parallel to the major surfaces of the PZT elements electrically insulated from the load beam. Electrical connections to the PZTs are made via wires, solder, conductive epoxy or electro-mechanical attachment of a plated surface of the PZT with a bond pad on an electrically isolated substrate. Lead extensions or separate pieces may be used to connect to the PZTs. The PZTs may be located on a major surface of the load beam, or may be assembled in a pre-fabricated motor assembly before being installed in the head suspension. Apertures in the load beam and other layers permit physical installation of the PZT motors and enable electrical connection to the PZTs.

摘要： Servo tracks are written onto different disk surfaces using multiple recording heads within a disk drive without requiring a servo writing machine or clean room conditions. Microactuators in the reference heads in the disk drive are capable of independent motion with respect to one another, which allows the servo tracks to be written to the disk surfaces. The process begins as the recording heads are biased against a crash stop, and then moved to an adjacent track. One of the heads writes a reference track at this adjacent track position when a microactuator of the head is centered. This reference head then follows the reference track with its microactuator centered, while the other recording heads move in the radial direction to write servo information on their respective tracks. Reference tracks are then successively used to write the servo information as the recording heads move in a direction away from the crash stop.

摘要： A method of operating a disk drive including providing the disk drive. The disk drive includes a disk with data tracks and an actuator with a slider including a perpendicular magnetic write head. The write head includes leading and trailing sides defining a taper angle. The write head and the actuator define a maximum skew angle with respect to the data tracks.
