Abstract
The mechanical texturing of recording media which is necessary for good stiction characteristics can have an undesirable side effect on magnetic performance. A simple technique is described to measure the modulation noise caused by the texture in the substrate. Measurements made on CoPtCr media show a strong connection between the degree of modulation and the error rate
