摘要： PURPOSE:To position a magnetic head with high accuracy and good reproducibility by making stationary a driven body once immediately before a marker stationary position and next, shifting to the marker stationary position. CONSTITUTION:A step motor to position a magnetic head of a magnetic disk is provided with a winding at the internal part, and rotated by the signal to give the number of shifting tracks of the stationary position inputted to a driving circuit and the signal to give the shifting direction while the electric current of the winding is successively changed over at the changing-over circuit. In this way, for example, a motor is rotated so as to shift the magnetic head which is stationary at a track number 2, up to a number 6. At this time, the magnetic head is stopped once immediately before the marker position (track No.6), after that the head is driven again and positioned to the marker position, and as the result, an excessive response condition at the time of stoppage is always made constant. For this reason, a stop position error due to the difference of the settling condition at the time of stoppage can be deleted.
摘要翻译：目的：通过在标记固定位置之前立即将驱动体固定一次，然后移动到标记固定位置，以高精度和良好的重现性来定位磁头。构成：用于定位磁盘的磁头的步进电机在内部设置有绕组，并且由信号旋转以给出输入到驱动电路的静止位置的移动轨迹的数量，并且给出信号绕组的电流在切换电路上依次切换时的移动方向。以这种方式，例如，电动机被旋转以使在磁道号2处静止的磁头移动到数量6.此时，磁头在标记位置（轨道）之前立即停止在此之后，再次驱动头并定位到标记位置，结果，停止时的过度响应条件总是保持恒定。因此，可以删除由于停止时的稳定条件的差异引起的停止位置误差。

摘要： PROBLEM TO BE SOLVED: To reduce the risk of a third party referring to or using backup data upon restoring such backup data in an HDD recorder.
SOLUTION: First authentication information of a user as the HDD owner and second authentication information of an engineer of a repair plant are registered in an online backup service system. The first authentication information is used when backing up data recorded in the HDD to the online backup service system, and the second authentication information is used when restoring the data backed up to the online backup service system. The data backup processing and data restoration processing are executed only when the authentication information is appropriate. Since the user will directly receive an e-mail from the online backup service system regarding who restored which data at what time, such user will be able to audit the data restoration process independently from the person recovering the data.

摘要： PURPOSE:To remove moment that acts to increase wear of sliding parts of the head assembly of a magnetic disk device and its guide mechanism by providing a moment removing device that acts in opposite direction to moment when moment of rectilinear moving force caused by a belt acts in a direction different from specified direction. CONSTITUTION:A belt 3 is wound on a pulley 2 spirally, and its both ends are fixed to the head assembly, and made asymmetric to the rotation shaft (shaft 10) of a step motor 1. Consequently, when a head assembly 5 is driven by the step motor 1, rotational moment acts to the head assembly 5 around the center of the belt 3 in the direction shown by the arrow mark A. By this rotational moment, force acts in the direction of the arrow B and the arrow C in which friction is promoted. The force becomes a factor that causes partial wear of the head assembly and increase azimuth angle. However, this force is canceled by the force of a repulsing member 11 that acts in the direction of the arrow mark D.
