A new scheme for finite element analysis of an interface phenomena of VCR drum, head and tape

A numerical scheme for the finite element method (FEM) used for calculating the mechanical interface phenomena in a video cassette recorder (VCR), namely, between the tape, the head and the drum, is presented. To permit estimation of the characteristics of the VCR system and the effects of design parameters on the performance, it was necessary to reduce CPU time and memory storage without losing accuracy. The analysis area was divided into two subareas, a whole drum area and a head circumference area. The analysis for the latter area was carried out based on the results for the former area. The analysis results were in good agreement with experimental data and required a short computation time
