Patent ID: 8477589

Claim:
An optical pickup that at least writes data on or reads data from an optical disc using a laser light beam, the optical pickup comprising: an optical pickup optical system including an optical lens and an optical mirror; a flexible printed circuit disposed above the optical pickup optical system; a heat dissipation cover disposed above the flexible printed circuit; a laser diode driver configured to generate a write strategy signal or a high frequency modulation signal; a first laser diode using the write strategy signal or the high frequency modulation signal for a drive current and configured to output a laser light beam modulated based on the drive current; a first line formed on the flexible printed circuit and configured to connect a first port of the first laser diode to a port that provides a fixed potential; and a second line formed on the flexible printed circuit and configured to connect a second port of the first laser diode to an output port of the laser diode driver, wherein: the first line and the second line form a two layer structure in which the first line and the second line are faced in a vertical direction to be a stacking direction of the flexible printed circuit at at least one location or more; and a line width of the line formed on the heat dissipation cover side between the first line and the second line is wider than a line width of the line formed on the optical pickup optical system side in a direction orthogonal to the stacking direction.
