FINITE-ELEMENT ANALYSIS OF TAPE-HEAD INTERFACE PHENOMENA OF VCR

A new numerical scheme for calculating the interface phenomena of VCR, namely between magnetic tape and head or drum, is presented. To enabl e estimation of the characteristics of the designed VCR system and eff ects of design parameters on the performance, it is necessary to reduc e the CPU time and memory storage without sacrificing accuracy. We div ide the area to be analyzed into two sub-areas: entire drum area and h ead area. These are analyzed separately, with the result for the forme r being used in the analysis of the latter. The results obtained are i n good agreement with experimental ones.
