Finite-Element Analysis of Tape-Head Interface Phenomena of VCR

Abstract

A new numerical scheme for the finite element method for calculating the interface phenomena of VCR, namely, between the magnetic tape and the magnetic head of the drum, is presented. To enable estimation of the characteristics of the designed VCR system and the effects of design parameters on the performance, it is absolutely necessary to reduce the CPU time and the memory storage without losing accuracy. We divide the analysis area concerned into two subareas, a whole drum area and a head circumference area. The analysis is carried out in one after another, and the result is used for the other analysis. The analysis results are in good agreement with the experimental one. Moreover, the CPU time required to carry out the analysis is short.
