    • A system and method for monitoring fly height between a magnetic recording medium and a transducing head. In a first exemplary embodiment, magnetic spacing change value is calculated using media noise on the recording medium (instead of prerecorded tones) to provide a broadband frequency distribution that results in improved Wallace equation accuracy. In a second exemplary embodiment, a magnetic spacing change value is acquired by any suitable method but is adjusted as necessary to reflect transducing head wear, thus providing a methodology for calculating changes in fly height by taking into account the signal loss that is attributable to wear. In this way, a basic understanding of the mechanism causing changes in magnetic spacing is achieved.
    • 一种用于监测磁记录介质和换能头之间的飞行高度的系统和方法。 在第一示例性实施例中,使用记录介质上的介质噪声(而不是预先记录的音调)来计算磁间隔变化值,以提供导致改进的Wallace方程精度的宽带频率分布。 在第二示例性实施例中,通过任何合适的方法获得磁间隔变化值,但是根据需要进行调整以反映换能头磨损,从而提供用于计算飞高度变化的方法,其中考虑到由于磨损引起的信号损失 。 以这种方式,实现了引起磁间距变化的机理的基本理解。
