Abstract
A method for evaluating bit error rate for a magnetic head by using a quasi-static test system, includes step (a), measuring a noise characteristic curve for a magnetic head, and the noise characteristic comprising noise amplitude and maximum noise amplitude; step (b), constructing a noise waveform by appropriately scaling a signal noise ratio of the magnetic head based on the noise characteristic curve measured in step (a); and step (c), injecting the noise waveform constructed in step (b) into a model comprising a transmitter module and a receiver module to evaluate a bit error rate. The method saves testing time, reduces manpower, and obtains accuracy testing result.
