Abstract
An optical head having a semiconductor laser that emits a laser beam, an optical system that leads the laser beam emitted by the semiconductor laser onto a recording medium, an optical power detector that detects the power of the laser beam emitted by the semiconductor laser, and a variable resistor that adjusts the detection output released by the optical power detector. The adjustment performed by the variable resistor enables to suppress readily the fluctuation of the detection output occurring with every optical head manufactured.
