The simulation of the spacing between a magnetic head and medium has been done to investigate the spacing characteristics for the head shape on a video floppy. In this simulation, the finite-element method is used to solve Reynold's equation and the equation of motion for the transformation of medium. Both the equations are discretized simultaneously. The following results were obtained by this analysis: 1) This method efficiently obtains a convergent solution despite the non-linearity of these equations. 2) The spacing has a tendency to be constant for the head protrusion. 3) The effect of the groove on the head surface is the same as that of the narrow track width of the head. 4) For actual use, sufficient depth and width of the groove are more than 2 μm and 5 μm, respectively.
