The present invention provides a new approach for processing hyper-spectral radiance data. The surface finish of the member is chosen to help keep the components which it partly surrounds isothermal during operation. The combined signal comprises the plurality of data signals. Manufacturing method for slider, head gimbal assembly, head stack assembly and hard disk drive, and these items as products of these processes. The loaded, and translated, resource is then checked against validation rules to see if it is safe to use.
