Abstract
An optical disk device of the present invention has a main PC board carrying a semiconductor element and attached at the rear of a drawer to efficiently dissipate a heat generated from the semiconductor element. The drawer is formed of a material having good thermal conductivity. A thermal conductive member having good thermal conductivity is interposed between the IC desired to be dissipate heat and the drawer.
Claims3
An optical disk device, comprising:
- a mechanical chassis carrying a driving mechanism supporting and controlling the rotation of an information recording medium, and a pickup head;
- a substrate mounting a semiconductor element at least for a driver IC and an IC for an AMP;
- a drawer mounting the mechanical chassis and the substrate, and formed at least partly using a material having good thermal conductivity,
- a thermal conductive member that is interposed between the semiconductor element of the substrate and the drawer, and transfers heat generated from the semiconductor element by contacting the semiconductor element;
- and
- a bottom plate that holds the drawer in a slidable manner, wherein
- the thermal conductive member transfers heat of the semiconductor element so that the heat is radiated from a front surface of the drawer.
