Abstract

Actuator (1) for use in an optical pick-up unit comprising a moveable lens holder (2), holding a lens (5), and a retaining structure (4), the actuator (1) comprising a coil system (6) and a magnet system (7), configured to interact with each other during use to move the lens holder (2) with respect to the retaining structure (4), wherein a first part of the coil system (6) is arranged opposite a first side (7a) of the magnet system (7) and a second part of the coil system is arranged opposite a second side (7b) of the magnet system (7), said second side (7b) being faced away from said first side (7a); and optical pick-up unit, preferably for a notebook, comprising such an actuator (1).
