ABSTRACT:
A head positioning device for a disk drive unit comprises a Y-shaped drive band for displacing the carriage bearing the head(s), each divergent arm portion of the Y forming the same angle with the central longitudinal axis of the band. In another embodiment, the two divergent arm portions are connected together by a crosspiece. Advantageously, the drive band is made of steel having a tensile strength of from 1200 to 2500 N/mm.sup.2, especially from 2000 to 2500 N/mm.sup.2. The novel positioning device can be used with advantage in any type of system for recording, reproducing and storing audio, video, data or control signals.
