摘要： A disk drive having an arm assembly equipped with a primary actuator such as a VCM and a mode-canceling actuator such as a PZT mounted at a location selected in such a way that the strain in the mode-canceling actuator is in phase with sway deformations of the primary actuator produced by the vibrational modes of the arm assembly. The primary actuator is driven to exert a primary force, f ⋁ pm , on the arm assembly while the secondary driver ensures that the mode-canceling actuator applies a mode-canceling force, f ⋁ m ⁢ ⁢ c , on arm assembly such that the gain and phase of one or more vibrational modes are canceled.

摘要： An actuator assembly having two coils disposed between the poles of a voice coil motor (VCM) magnet for improved dynamic performance during settling and tracking operations in a disk drive. The two coils in the VCM are connected to separate current sources to allow the current flow in the two coils to have the same sense (clockwise or counterclockwise) or the opposite sense with respect to each other. When the current flows in the two coils have the opposite sense, excitation of the principal in-plane bending mode resonance of the actuator assembly is suppressed allowing the use of an increased servo bandwidth for settling and tracking operations of the disk drive. During seek operations of the disk drive, where maximum torque on the actuator is desirable, the coil currents in the two coils are chosen to have the same sense so that the forces on the actuator from the two coils are additive.

摘要： A system and method for using a piezoelectric (PZT) element to simultaneously actuate and sense a displacement of an arm assembly; e.g., an assembly for reading and writing data in a storage medium. The simultaneous actuating and sensing function of the PZT is achieved by adding a high-frequency excitation to a control signal which actuates the PZT. The control signal and the high-frequency excitation cause deformation of the PZT translating into arm displacement and cause the generation of an electrical response signal by the PZT. A bridge which simulates the reactance/resistance of the PZT receives the response signal and derives from it the displacement of the arm assembly. Suitable compensation techniques for active control of the PZT and for mitigation of mechanical vibrations and other disturbances experienced by the arm assembly may then be implemented based on the displacement.

摘要： An active control mechanism and method for stabilizing a servo-controlled actuator system such as an actuator system in a data recording disk drive by compensating the vibrational modes of the actuator's arm assembly. The control mechanism has a sensing arrangement which can include one or more individual sensors attached to the actuator at locations where they generate signals in phase with the vibrational modes, and especially with all the major vibrational modes, of the arm assembly. A control mechanism derives from the signals an adjustment signal consisting of three corrective terms--a stiffening correction, an active damping correction and an inertia reduction correction--and the adjustment signal is used in the feedback control loop to stabilize the actuator system.

The arm assembly has a first arm with a first proximal flex region next to the pivot and a distal flex region at the other end of the arm and a second arm with a second proximal flex region next to the pivot and a second distal flex region at the other end of the second arm. The two arms are joined at their distal ends by a terminal piece equipped with a controlled element, such as an optical or magnetic read-write head or a sensor. A control mechanism which can include VCM coils, MEMs, piezoelectric elements or the like is provided to drive the arm assembly and cause it to execute two motions: rotation about the pivot and flexing at the proximal and distal flex regions which causes the terminal piece to rotate. thus adjusting the position of the controlled element. The rotation about the pivot and rotation of the terminal piece adjust the position of the controlled element.

摘要： In one embodiment, a tape read/write head supported by a lever is biased in a first position, using magnetic attraction between a magnet supported by the lever, and a return path structure of magnetically permeable material. In the illustrated embodiment, the magnet centers itself, in the absence of a coil generated magnetic field, in the middle of a gap of the magnetic return path structure. In one aspect, the mass of the read/write head and one side of the lever may be balanced by the mass of the magnet and the other side of the lever. The lever and hence the tape read/write head carried by the lever, may be pivoted by conducting current through a coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. As a consequence, the lever pivots on a pivot axis as a function of the magnitude and direction of the current through the coil. The face of the magnet may be divided into portions of opposite magnetic polarity to facilitate a relatively pure torque to be developed substantially without a net force. Other embodiments are described and claimed.
