| 摘要 |
Provided is an optical disk apparatus that suppresses shortening of the life time of a light source, degradation of the signal quality involved in an increase in quantum noise, and lowering of the slope efficiency, which are caused by a temperature increase of the light source by a lowering in the heat radiation performance of the light source due to size reduction or thickness reduction of the apparatus. As a specific structure, the optical disk apparatus includes an optical pickup including: a light source; a light source drive circuit; an optical base housing an optical system for guiding light emitted from the light source to a disk-shaped recording medium; a first heat radiation member connected to the light source; and a second heat radiation member connected to the light source drive circuit.
