Abstract:
(EN) Provided are a simple, practical method for manufacturing a bit pattern type or the like magnetic storage medium, as well as a magnetic recording medium of the aforementioned type and an information storage device which can be manufactured with this type of simple, practical manufacturing method, In a method for manufacturing a magnetic disk, a film formation step (A), in which a magnetic film (62) is formed on a glass substrate (61) with a Curie temperature of 600K or less, and an ion implantation step (C), in which ions are locally implanted in said magnetic film (62) in a region other than a specific protective region, are performed.
(FR) L'invention concerne un procédé simple et pratique permettant de fabriquer un support de stockage magnétique du type à motif binaire ou similaire, ainsi qu'un support d'enregistrement magnétique du type susmentionné et un dispositif de stockage d'informations qui peut être fabriqué avec ce type de procédé de fabrication simple et pratique. Dans un procédé permettant de fabriquer un disque magnétique, une phase de formation de film (A), dans laquelle un film magnétique (62) est formé sur un substrat en verre (61) avec une température de Curie de 600 K ou inférieure, et une phase d'implantation ionique (C), dans laquelle des ions sont localement implantés dans ledit film magnétique(62) dans une région autre qu'une région de protection spécifique, sont réalisées.
(JA)  ビットパターンド型等といったタイプの磁気記憶媒体を製造可能な簡易で現実的な製造方法、そのような簡易で現実的な製造方法で製造可能な上記タイプの磁気記憶媒体および情報記憶装置を提供することを目的とし、磁気ディスク製造方法において、ガラス基板61上に、キュリー温度が600K以下となるように磁性膜62を形成する製膜工程(A)と、その磁性膜62に対し、所定の保護領域を除いた他の領域に対して局所的にイオンを注入するイオン注入工程(C)とを実行する。
