摘要： PROBLEM TO BE SOLVED: To provide a micro-optical pickup capable of effectively increasing the reading speed of the optical pickup. SOLUTION: A dynamic micro-machined optical device is applied in a micro-optical pickup. The micro-optical pickup includes an actuator and a dynamic grating, wherein the actuator is a cantilever beam electrostatic actuator, a scratch drive actuator, a magnetic actuator or an electromagnetic actuator, and the actuator is controlled by applying an external voltage. The position of the dynamic grating is switchable between on and off the optical axis. When the external voltage is applied, the on-axis dynamic grating splits the light from a laser diode into multi-beams and the micro-optical pickup rapidly reads multi-track information on the disk with multi low energy beams. When the external voltage is turned off, the dynamic grating is off the optical axis and the light from the laser diode passes directly and write information into the disk with single high energy beam.
