摘要： An actuator having a simple configuration requiring no high dimensional accuracy, high in positioning accuracy and low in cost, and a head-positioning mechanism using the actuator are disclosed. An actuator according to a first application comprises a shear-type piezoelectric element of predetermined thickness and an opposed electrode formed on two electrodes in spaced relationship on a base member. The opposed electrode is displaced in accordance with the direction of polarization of the shear-type piezoelectric element upon applying a voltage between the two electrodes. The opposed electrode thus constitutes an operating section of the actuator. An actuator according to a second application comprises a movable member arranged on a drive member including a shear-type piezoelectric element on a base member. The drive member includes a plurality of layers of piezoelectric elements polarized in alternately opposite directions perpendicular to the thickness of the devices. A plurality of conductive layers are formed adjacently to the respective layers of the devices to permit voltage application thereto. The movable member can be driven in parallel to the base member upon application of a voltage between the conductive layers. Any one of these actuators can be incorporated as a part of the head actuator to constitute a head-positioning mechanism capable of displacing the head by a minuscule distance independently of the operation of the head actuator.

摘要： A method for incorporating a disk medium into a magnetic disk drive, in which the rotation center of the disk medium when a servo track information is written onto the disk medium (STW) coincides with the rotation center thereof when the disk medium is incorporated into the disk apparatus. A reference marker is provided as a positioning reference on a part of the disk medium. The disk medium is incorporated into a STW apparatus so that STW is performed on the disk medium. The disk medium is also incorporated into the magnetic disk drive in such a manner that a distance from an axis of rotation center of the disk medium to the reference marker is the same as when the STW was performed onto the disk medium.

摘要： According to one embodiment, a carriage assembly includes a carriage block body, a carriage arm, a coil, a pair of support arms, and a frame body. The carriage block body is rotatably connected to a spindle. The carriage arm extends forward from the front of the carriage block body. The coil is located behind the carriage block body, and defines a linear region extending along a reference straight line extending radially from the center of the spindle. The support arms extend in parallel to the linear region from a back surface of the carriage block body. The frame body is made of a resin material, and fills between the coil and the support arms to couple the coil and the support arms. The support arms extend more outside than the external end of the linear region of the coil in the radial direction.

摘要： A balance correction apparatus is configured to correct weight imbalance around an axis of a spindle motor, and includes a piezoelectric actuator configured to apply an impact to a housing, a controller configured to generate as a rectangular wave a force profile that represents an acceleration applied to the housing by the piezoelectric actuator, and a waveform generator configured to generate a voltage waveform configured to drive the piezoelectric actuator, by integrating the force profile twice. The rectangular wave has a first acceleration after a leading edge and a second acceleration after a trailing edge. The first acceleration enables the disc to move relative to the spindle motor and the housing. The second acceleration enables the disc to move together with the spindle motor and the housing.
