本発明は、磁気テープに関し、深層記録方式に使用する
磁気テープに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic tape, and more particularly to a magnetic tape used in a deep recording method.
一般に、磁気テープは、磁性体がテープ面に対し水平方
向の磁化特性を持つ塗布型と、テープ面に対し垂直方向
の磁化特性を持つ蒸着型がある。Generally, there are two types of magnetic tape: a coated type in which the magnetic material has magnetization characteristics in a direction horizontal to the tape surface, and a vapor deposited type in which the magnetic material has magnetization characteristics in a direction perpendicular to the tape surface.
従来の磁気テープは、深層記録方式により複数の信号を
記録した場合、表層の信号（磁気）と深層の信号（磁気
）が干渉、転写してしまう為、経時劣化が太きいという
欠点がある。Conventional magnetic tapes have the disadvantage that when multiple signals are recorded using the deep recording method, signals in the surface layer (magnetism) and signals in the deep layer (magnetism) interfere and are transferred, resulting in severe deterioration over time.
本発明の磁気テープは、塗布層と蒸着層の二種類の磁性
層を有している。この様にすることにより、表層と深層
で磁化の方向が垂直になり、表層の信号（磁気）と深層
の信号（磁気）の間の干渉をなくす事が出来る。The magnetic tape of the present invention has two types of magnetic layers: a coating layer and a vapor deposited layer. By doing this, the direction of magnetization becomes perpendicular between the surface layer and the deep layer, and it is possible to eliminate interference between the signal (magnetism) in the surface layer and the signal (magnetism) in the deep layer.

させる効果がある。As is clear from the above explanation, according to the magnetic tape of the present invention, by making the directions of magnetization in the surface layer and deep layer perpendicular, interference between signals (magnetism) in the surface layer and deep layer can be eliminated and deterioration over time can be reduced. be.
以下に、本発明について図面を参照して説明する。 The present invention will be described below with reference to the drawings.
