Title
(EN) TAPE HEAD WITH THIN TAPE BEARING SURFACE COATING
(FR) TÊTE DE BANDE AVEC REVÊTEMENT MINCE DE SURFACE DE SUPPORT DE BANDE
Abstract
(EN)
A tape head is provided for use with a tape drive that is configured to receive a length of tape. The tape head includes a head body including at least one head element for performing read and/or write operations on the tape, and a protective layer extending over at least a portion of the head body for inhibiting wear of the head body when the tape is moved with respect to the head body. Furthermore, the protective layer is made of titanium oxide, chromium oxide, zirconium oxide, aluminum oxide, or zinc oxide.
(FR)
Cette invention concerne une tête de bande conçue pour être utilisée avec un dispositif d'entraînement de bande configuré pour recevoir une longueur de bande. Ladite tête de bande comprend un corps de tête comprenant au moins un élément de tête pour effectuer des opérations de lecture et/ou d'écriture sur la bande, et une couche de protection s'étendant sur au moins une partie du corps de tête pour l'inhibition de l'usure du corps de tête lorsque la bande est déplacée par rapport au corps de tête. Par ailleurs, ladite couche de protection est constituée d'oxyde de titane, d'oxyde de chrome, d'oxyde de zirconium, d'oxyde d'aluminium, ou d'oxyde de zinc.
