  • Disk pack swap process for evaluating magnetic recording performance
    Patent number: 7248039
    Abstract: A method for testing electromagnetic characteristics of magnetic media while maintaining consistent performance of a read/write head and recording channel is disclosed. The disclosed method is performed such that reduced statistical sampling is achieved. The method includes recording a first set of baseline measurements utilizing a first magnetic media with the read/write head and recording channel. The first magnetic media is then removed from an assembly containing the read/write head and recording channel and is replaced with a second magnetic media. Measurements are made utilizing the second magnetic media with the read/write head and recording channel, wherein the measurements are comparable with the baseline measurements and wherein consistent performance of the read/write head and the recording channel is maintained so as to reduce the size of statistical samples needed.
