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