Thin Fe-Si-AI-N films have been developed for the main pole of single-pole heads. This film has good magnetic properties, including a high saturation magnetization of 1080 emu/cc, a high permeability of 2500, and a low coercivity of 0.3 Oe, even if the film thickness is 0.23 pm. A narrow-track single-pole head having a main pole 2.6 rm wide and 0.23 pm thick was made using Fe-Si-AI-N film and its read-write characteristics were investigated. In combination with a Co-Cr/Ni-Fe double-layer flexible disk medium, a normalized reproduced voltage of about 75 nVo_p/pm'Tom/s and a CN ratio of 51 dB were obtained at 50 kFRPI(about 6 MHz).

Previously, it was stressed that the magnetically soft amorphous films lose their softness when nitrogen or oxygen is doped in the fabrication process. However, it has been reported that composition‐modulated nitride films maintain magnetic softness and exhibit remarkably high thermal stability. Furthermore, it has been reported that uniform nitride films with magnetic softness can be obtained when deposited by ion beam sputtering. In this paper, uniform nitride films deposited by dc magnetron sputtering are studied. DC magnetron sputtering is expected to have an effect similar to that of the nitride films in improvement of magnetic softness. The results of the analysis of nitrogen content and its chemical bonding and magnetic softness of the films are described. Furthermore, the transition process from the amorphous phase to the nanocrystalline phase and the structure of the crystalline phase are studied. The results suggest that the films have a magnetic structure different from that of the magnetically soft nanocrystalline materials reported so far.
