Abstract
Noise, which is generated in a read amp of a hard disk drive (HDD), is analyzed by using the moment method. The noise source is assumed to be a near-by interface cable. From the results of the analysis, the methods used to decrease the noise are shown to be effective. In addition, it is shown that the noise is affected by the grounding method between signal ground (SG) and frame ground (FG)
