    • A laser beam power studying system and method. A laser beam is emitted and a power of the laser beam at a position to be incident on a recording medium is measured. A part of the laser beam is converted to a photovoltage signal corresponding to an amount of the laser beam and amplified with reference to a reference voltage signal to provide an output voltage signal. A difference between the output voltage signal and the reference voltage signal is obtained at a plurality of different laser beam power levels, to derive a difference to laser beam power correlation.
