Abstract: A compact and simple lapping apparatus in which, even if projections and depressions are formed in the circumferential direction on the top surface of a lapping plate, a workpiece and a bar are hard to damage and the polished surface of the workpiece is kept in good condition. This apparatus is provided with at least one lapping jig in which a workpiece is placed on the rotating top surface of the lapping plate. Further, a lapping head adapted to be able to rotate only in a direction on the lapping plate is attached to this lapping jig. This lapping head is equipped with a workpiece and at least two dummy work materials (or stock) so that these dummy works compose (as-polished) surfaces, which should be polished, together with the workpiece. Moreover, a device for detecting the remaining part of the workpiece to be lapped is provided on the workpiece. Furthermore, this lapping apparatus is configured so that a detection signal, which represents the detected remaining part of the workpiece and is outputted from the rotating lapping head, is sent to and a correction signal is sent from a control unit to the lapping correction device through a slip ring. A workpiece is polished while rotated on the lapping plate. Thus, the polished surface of the workpiece is kept in good condition.

Abstract: 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.

Abstract: 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.
