A new computer-based self-correcting calibration system for computer storage media standard reference materials

Abstract

A new method for calibrating magnetic computer storage media Standard Reference Materials (SRMs) has been developed at the National Bureau of Standards (NBS). This calibration system applies to a new class of higher density Standard Reference Magnetic Computer Storage Media. The foundation of this method is based on both the analysis of and experience with the present well-established SRM calibration systems. Errors that would be introduced into the calibration process by unwanted system changes are prevented from doing so through the use of self-correcting techniques. The data which are automatically produced by these techniques also simplify the calibration process. The outputs from this new calibration method provide the users of these high density Standard Reference Materials with information which is easily related to the Master Reference media saturation curve. The development of magnetic computer storage media Standard Reference Materials (SRMs) is also described.
