Abstract
It is anticipated that the near-field recording method will become one of the promising candidates for realizing high density optical recording sensor head to satisfy the demands of storage capacity in computer communication society. In this paper, we propose a novel optical contact head slider which cancels the suspension load by generating hydrodynamic total pressure. We introduce a mixed lubricantion model for basic design and 2-degree-of-freedom vibration model could successfully confirm-its mechanical responses when sliding on minute wavinesses of a metal coated medium. Detailed analysis reveals the non-linear response of the amplitude of the waviness. Experimental confirmation on the trial-manufactured optical contact slider will be performed in the near future.
