Head keeper spacing (HKS) is an important parameter in the keepered perpendicular magnetic recording. In this paper, a nondestructive method to measure HKS from the playback waveform of a specific recording pattern was proposed. Time and frequency domain techniques can be utilized for the measurements. The measured HKS was shown to be consistent by using different playback harmonic peaks. The effect of head surface potential distribution due to the HKS change was also discussed
