Patent ID: 8045425

Claim:
An optical disk apparatus comprising: a light source for emitting a light flux; a light source drive circuit for causing the light source to emit the light flux; an optical base having an optical system disposed thereon, the optical system comprising an objective lens for guiding the light flux emitted from the light source to a disk-shaped recording medium; a moving mechanism for moving the optical base; a first heat radiation member connected to the light source; and a second heat radiation member connected to the light source drive circuit and being different from the first heat radiation member, wherein the first heat radiation member and the second heat radiation member are provided so as to face the disk-shaped recording medium, and wherein the first heat radiation member is disposed on the disk-shaped recording medium side with respect to the second heat radiation member, and the first heat radiation member has a hole provided therein, for exposing the second heat radiation member to the disk-shaped recording medium.
