Abstract
An analysis of recording characteristics on magnetic tape recording systems was described. The magnetization transition parameters were calculated by the simplified vector field model proposed by Bertram et al. [1]. To get accurate results, the head field were generated by finite element methods(FEM) instead of the Karlqvist function. This technique enables us to characterize aspects of the recording process and can be used to show the effect of head-medium parameter changes: head structures, magnetic characteristics of head materials, medium thickness, and medium coercivity. This paper also describes the playback voltage versus recording current for metal film thickness in Metal-In-Gap(MIG) heads and medium thickness, including experimental comparisons.
