Abstract

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.
