Title
(EN) LEADER TAPE AND MAGNETIC TAPE CARTRIDGE EMPLOYING THE SAME
(FR) RUBAN DE GUIDAGE ET CHARGEUR DE BANDE MAGNÉTIQUE QUI L’UTILISE.
(JA) リーダーテープおよびこれを用いた磁気テープカートリッジ
Abstract
(EN)
There is provided a leader tape capable of suppressing increase in drop out incident to impression of a drive reel or a leader block part due to long term preservation or traveling under high temperature and not causing edge damage of a magnetic tape. A magnetic tape cartridge employing the leader tape is also provided. [1] In a leader tape LT provided with a coating layer at least on one side of a support, the leader tape LT has Ra of 10-60 nm at least on one side thereof and a maximum curvature L of 3 mm/m or less in the longitudinal direction of the leader tape. [2] In a magnetic tape cartridge for rotatably containing a single or a plurality of reels formed by winding a magnetic tape around a cartridge case, the leader tape of [1] is employed as a leader tape attached to the forward end of the magnetic tape and drawn into a magnetic recorder/reproducer while leading the magnetic tape.

Il est fourni une bande de guidage capable de supprimer les incidents de pertes d’impressions causé par un axe de guidage ou partie d'un block de guidage liés un stockage à long terme ou à un transport sous des températures élevées et qui n'endommage pas les bordures d’une bande magnétique. Une bande de cartouche magnétique qui utilise la bande de guidage est aussi fournie. [1] Dans une bande de guidage LT fournie avec une couche traité ayant au moins une partie d’un support traité, la bande de guidage LT a Ra de 10-60nm sur au moins un côté présenté et un maximum de rayon de courbure L de 3mm/m ou moins dans le sens longitudinal de la bande de guidage. [2] Dans un chargeur de bande magnétique pour contenir de manière rotative un ou plusieurs axes formé en enroulant une bande magnétique autour d’un tube de cartouche, la bande de guidage de [1] est utilisé comme bande de guidage attachée à l'extrémité de la bande magnétique et menée à magnétophone à bande/lecteur magnétique tout en dirigeant le ruban magnétique.
