A low-mass head/flexure/conductor assembly for reading and writing information with respect to a rigid magnetic recording disk. The assembly includes a read/write transducer unit, an elongate flexure, and gimbal structure interconnecting and articulating the transducer unit and the flexure for selected, limited relative roll and pitch, without relative yaw. Conductive ribbons that form part of the gimbal structure also form part of the conductive circuit provided in the assembly. The assembly has an effective mass of no more than about 1.5-milligrams. Plural, hardened, wear-resistant feet are formed on the transducer unit for enabling sliding contact with the recording surface in a disk.
Cette invention concerne un ensemble tête d'écriture/lecture-support-conducteur allégé destiné à l'enregistrement et à la lecture d'informations sur un disque d'enregistrement magnétique rigide. L'ensemble comprend un transducteur d'écriture/lecture, un support allongé et, entre les deux premiers, une suspension à la cardan autorisant un roulis et un tangage relatifs limités sans lacet aucun. Les rubans conducteurs qui font partie de la suspension à la cardan font également partie du circuit conducteur de l'ensemble. Celui-ci a une masse effective d'au plus 1,5 milligramme environ. Le transducteur comporte plusieurs patins durcis et résistants à l'usure destinés à glisser à la surface d'enregistrement du disque.
