L'enregistrement à tête annulaire sur un support d'enregistrement perpendiculaire monocouche a été étudié par une analyse de simulation simple basée sur une méthode de traçage de boucle considérant uniquement la composante perpendiculaire. Bien que le modèle supposé soit primitif, les résultats de la simulation expliquaient qualitativement bien les résultats expérimentaux tels qu'une diminution de la sortie à des courants d'enregistrement élevés et sa relaxation lors de l'utilisation d'une tête de plus petite longueur d'intervalle. Les résultats de la simulation ont révélé que la magnétisation enregistrée réalisable est, en général, bien inférieure à la valeur de saturation en raison d'une large distribution du champ de la tête annulaire, mais qu'un support avec une pente plus raide dans la boucle MH perpendiculaire pourrait améliorer les performances d'enregistrement. Cela a été confirmé expérimentalement pour le milieu avec une pente de boucle plus raide, bien que le milieu présente un bruit moyen plus important à des densités élevées. Il a été suggéré que le développement de l'enregistrement perpendiculaire pour un rendement plus élevé et un bruit plus faible pourrait être réalisé pour les deux supports avec une pente de boucle faible et raide. Le premier devrait être amélioré au moyen de la tête d'enregistrement tandis que le second devrait être amélioré grâce aux médias. Une amélioration importante est attendue dans les deux cas.

Abstract: Ring head recording on single-layer perpendicular recording media was studied by a simple simulation analysis based on a loop tracing method considering only the perpendicular component. Although the assumed model was primitive, the simulation results qualitatively well explained the experimental results such as a decrease in output at high recording currents and its relaxation upon using a smaller gap-length head. The simulation results revealed that achievable recorded magnetization is, in general, much smaller than the saturation value due to a broad distribution of the ring head field, but a medium with a steeper slope in the perpendicular M-H loop could improve the recording performance. This was confirmed experimentally for the medium with a steeper loop slope, though the medium exhibited a larger medium noise at high densities. It was suggested that the development of perpendicular recording for higher output and lower noise could be performed for both media with a small and steep loop slope. The former should be improved by means of the recording head while the latter by the media. A large improvement is expected for both cases.
