In this study, the elastic modulus, one of the mechanical properties of magnetic heads and disks, was measured using an Ar gas cluster ion beam (Ar-GCIB). The measured elastic moduli were used to estimate the contact between head and disk surfaces using the Hertzian contact model, and the critical contact loads at which head wear occurs were estimated from that model. As a result, it was estimated that head wear occurs when the contact load between the head and disk exceeds 60 to 110 μN for the actual HDIs.
