Optical pickup and optical disc drive

An optical disc drive that at least writes data on or reads data from an optical disc using a laser light beam, the optical disc drive 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 digital signal processor configured to generate a control signal that instructs generating a write strategy signal or a high frequency modulation signal based on data to be written on or read from the optical disc;
• a laser diode driver configured to generate the write strategy signal or the high frequency modulation signal based on the control 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.
