摘要： A device inspects the performance of a perpendicular magnetic recording medium by separating the medium noise component of a perpendicular magnetic recording medium to decrease the error rate by accurately separating and detecting the medium noise component. Using correlation matrices, jitter noise and T50 noise which depend on the transition point of magnetization, and DC noise which is added to a DC component are separated and detected from the medium noise component of a perpendicular magnetic recording medium acquired from the reproducing waveform of a magnetic head. By adding a base matrix of the DC noise component to a linear separation expression for detecting the noise power from the medium noise component, the DC noise is detected using the least square method, separately from the other medium noise, which depends on the fluctuation of magnetization transition points.
