En mesurant les profils de pistes croisées d'une micropiste créée par DC effaçant les deux côtés d'une piste enregistrée, la dépendance linéaire de la densité d'enregistrement de la largeur de frange de la piste écrite et celle de la largeur de la frange de la piste lue ont été séparées avec succès, toutes deux généralement observées dans combinaison. Il a été précisé que lorsqu'une tête à couche mince est utilisée pour la lecture, la largeur de frange de la piste de lecture augmente à mesure que la densité d'enregistrement linéaire diminue, alors qu'elle reste presque constante lorsqu'une tête MR avec de larges couches de protection est utilisée. Il a également été précisé que la largeur de frange de la tête d'enregistrement pour une tête inductive à couche mince dépend moins de la densité d'enregistrement linéaire. Les effets de plusieurs têtes avec différentes formes de pôles sur les phénomènes de bord de piste ont également été évalués, en effaçant partiellement une piste écrite du bord de piste et en mesurant le changement dans la sortie résiduelle de la piste. Il a été constaté que la largeur du champ marginal d'une tête d'enregistrement change en fonction de la forme du pôle, et que le réglage des pôles de la tête d'enregistrement est très efficace pour réduire les effets marginaux du champ de tête.

Abstract: Measuring the cross-track profiles of a microtrack created by DC erasing both sides of a recorded track, the linear recording density dependence of the written track fringe width and that of the read track fringe width were successfully separated, both of which are usually observed in combination. It was clarified that when a thin-film head is used for reading, the read track fringe width increases as the linear recording density decreases, whereas it remains almost constant when an MR head with wide shielding layers is used. It was also clarified that the record head fringe width for a thin-film inductive head is less dependent on the linear recording density. The effects of several heads with different pole shapes on track edge phenomena were also evaluated, by partially DC erasing a written track from the track edge and measuring the change in the residual track output. It was found that the fringe field width of a record head changes depending on the pole shape, and the trimming of record head poles is very effective in reducing head field fringe effects.
