Abstract

A drive arrangement, for example for a writing head, comprising a piezoelectrically actuated lever arrangement (1d) for moving a writing tip (21) in the direction of a recording medium when writing on the recording medium. This drive arrangement is characterized in that a piezoelectric actuator (4) is used, which is separate from the lever arrangement (1d) and in that the lever arrangement (1d) exerts a compressive force on the piezoelectric actuator (4), which is supported against a rigid abutment (section 1b). This drive arrangement can be used for a series of other applications as a positioning drive. Inverse arrangements are also described.
