    • According to one embodiment, a frequency control apparatus includes an eccentric component storage module, a frequency correction amount calculating module, and an oscillator control module. The eccentric component storage module stores in advance an eccentric component calculated by a discrete Fourier transform of the number of clock signals measured for each servo frame. The frequency correction amount calculating module calculates the number of clock signals corresponding to the servo frame based on the eccentric component stored in the eccentric component storage module and calculates a frequency correction amount corresponding to the servo frame based on the number of clock signals. The oscillator control module controls the operation of a frequency oscillator such that a frequency for oscillating a clock signal in the frequency oscillator is adjusted according to the frequency correction amount calculated by the frequency correction amount calculating module.
    • 根据一个实施例,频率控制装置包括偏心分量存储模块,频率校正量计算模块和振荡器控制模块。 偏心部件存储模块预先存储通过对每个伺服帧测量的时钟信号的数量的离散傅里叶变换计算出的偏心分量。 频率校正量计算模块基于存储在偏心分量存储模块中的偏心分量来计算与伺服帧对应的时钟信号的数量,并且基于时钟信号的数量计算与伺服帧对应的频率校正量。 振荡器控制模块控制频率振荡器的操作,使得根据由频率校正量计算模块计算出的频率校正量来调整振荡频率振荡器中的时钟信号的频率。

    • A magnetic head slider comprises a slider body comprising a base portion made of an altic material and an element-forming portion, made of alumina, having formed thereon magnetic conversion elements. Slider-flying rails protruding beyond the surface of the slider body are provided. A first protection film is formed on the surface of the slider body to cover a boundary between the element-forming portion and the base portion to thereby prevent a lubricant of a magnetic disk from depositing on the boundary between the base portion and the element-forming portion. Second protection films are formed on the surfaces of the slider-flying rails to protect the magnetic conversion elements from being corroded and damaged. Further, when pneumatic bearings are provided on the slider-flying rails, third protection films are formed on the surfaces of the pneumatic bearings.
