Title
(EN) ACTIVE SPACING CONTROL FOR CONTACTLESS TAPE RECORDING
(FR) CONTRÔLE D'ESPACEMENT ACTIF POUR ENREGISTREMENT DE BANDE SANS CONTACT
Abstract
(EN) The present invention relates to the field of tape drives, tape transport, tape heads and tape head suspension. More particularly, the present invention is related to magnetic tape data storage and tape recorders that include components designed to minimize or eliminate head-to-tape contact to reduce or eliminate wear and contamination of tape drive heads. Methods and apparatus of the present invention may dynamically control the head-to-media spacing by moving locations of magnetic heads relative to a tape. Such apparatus may include components designed to minimize magnetic spacing. This may be accomplished using actuators that move the magnetic heads, that move the tape, or that move both the magnetic heads and the tape. This may include supporting a back surface of the tape. Alternatively, or additionally, the movement of the tape past the magnetic heads may be performed using mechanisms that contact and drive the back surface of the tape.
(FR) La présente invention se rapporte au domaine des entraînements de bande, de transport de bande, des têtes de bande et de la suspension de tête de bande. Plus particulièrement, la présente invention se rapporte au stockage de données de bande magnétique et aux enregistreurs de bande qui comprennent des composants conçus pour réduire au minimum ou éliminer un contact tête-bande afin de réduire ou d'éliminer l'usure et la contamination de têtes d'entraînement de bande. Les procédés et l'appareil de la présente invention peuvent contrôler de manière dynamique l'espacement tête-support en déplaçant les emplacements des têtes magnétiques par rapport à une bande. Un tel appareil peut comprendre des composants conçus pour réduire au minimum l'espacement magnétique. Ceci peut être accompli au moyen d'actionneurs qui déplacent les têtes magnétiques, qui déplacent la bande, ou qui déplacent à la fois les têtes magnétiques et la bande. Ceci peut comprendre le support d'une surface arrière de la bande. En variante, ou en outre, le mouvement de la bande au-delà des têtes magnétiques peut être effectué au moyen de mécanismes qui entrent en contact et entraînent la surface arrière de la bande.
