Laser diode driver, optical pickup device, and optical recording/reproducing apparatus using the same

摘要

Provided is an optical pickup device (700) which moves across a data storage medium, the optical pickup device comprising: a laser diode which generates a laser signal for recording/reproducing data on/from the data storage medium; and a laser diode driver which drives the laser diode; characterised in that: the laser diode driver moves with the laser diode across the data storage medium; and the laser diode driver controls power of the laser diode according to changes in temperature.
