Abstract

PURPOSE:To prevent the exfoliation of a magnetic material and back coat material and to prevent the generation of drop-out by forming preliminarily non- coating zones to both size edges of a film base. CONSTITUTION:A magnetic material film 3 is formed on one surface of the film base 1 made of a synthetic resin and a back coat material film 4 is formed on the other surface so that the non-coating zones 2 are formed at both side edges thereof. A tape T is then run along the front faces of magnetic heads 6, 7 of which the top ends are flush with the front face of a tape guide plate 5. The space B' between flanges 9 is made smaller than the width B of the tape T, by which the oscillation of the tape T in the transverse direction is prevented and even if the tape is rubbed by the flanges 9 of tape guides 8, the exfoliation between the films 3 and 4 is prevented by the zones 2 formed to the base.

Description

【発明の詳細な説明】 発明の技術分野 この発明は、磁気記録の媒体として使用する磁気テープ

発明の技術的背景及びその問題点 一般に磁気テープはその両側縁がテープガイドに支えら
れ幅方向の振れを阻止されて走行する。TECHNICAL BACKGROUND OF THE INVENTION AND PROBLEMS THEREOF In general, a magnetic tape is supported by tape guides on both sides thereof and runs while being prevented from wobbling in the width direction.

コート材料が剥離し易くなる欠点を有している。As a result, both side edges of the magnetic tape are rubbed by the tape guide, and the magnetic material powder or back coat material powder is peeled off, and these peeled off powders adhere to the magnetic head, etc., which tends to cause dropouts. In particular, when writing data on a 172-inch wide magnetic tape by subdividing it into 100 to 200 tracks, it is necessary to strictly suppress the deflection in the width direction of the magnetic tape, and the spacing between tape guides must be smaller than the width of the magnetic tape. It has to be made smaller. Therefore, both edges of the magnetic tape are seriously damaged, and the magnetic material and back coat material tend to peel off easily.
