Abstract: A system includes a host configured to communicate with a device under test. The host is configured to write test data to the device under test. An optimization engine is configured to optimize a plurality of parameters associated with a magnetic recording channel associated with the device under test. The optimization engine is configured to select a first set of parameters for the plurality of parameters and the host is configured to set the magnetic recording channel based on the first set of parameters. The host then measures the performance of the magnetic recording channel based on the first set of parameters. Based on the measured performance, the optimization engine then selects new parameter values for the plurality of parameters. Until the measured performance is within an acceptable threshold, the optimization engine will iteratively update the plurality of parameters based on the measured performance.
