Abstract: A hard disc drive includes a base deck, a cover welded to the base deck, and a voice coil motor. The voice coil motor includes a first voice coil motor assembly and a second voice coil motor assembly. Either one or both of the first and second voice coil motor assemblies can be welded to the base deck.

Abstract: A method for testing and grading electronic devices includes receiving a set of testing data associated with an electronic device that is following a testing routine. Based on the set of testing data, the method includes computing a first performance metric of the electronic device by using a first artificial neural network and computing a second performance metric of the electronic device by using a second artificial neural network. Based on at least the first predicted performance metric and the second predicted performance metric, the method includes computing a grade for the electronic device.

Abstract: A method is disclosed for establishing a fly height parameter for a hard disc drive. The method includes receiving a set of testing data associated with the hard disc drive and subjecting the hard disc drive to a fly-height test at a first, nominal temperature to generate fly-height data. Based on the set of testing data and the fly-height data, the method includes predicting the hard disc drive's fly-height data for a fly-height test at a second temperature different from the first, nominal temperature. The method further includes establishing the fly-height parameter for the hard disc drive in response to the fly-height data and the predicted fly-height data.
