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.
