Abstract
An optical disc recording device including a housing, an optical read/write module and a transmission module. Both the optical read/write module and the transmission module are disposed inside the housing. Besides, the housing includes a bottom housing and a top cover. The inner surface of top cover has a first protrusion and a second protrusion, which together can stabilize the flow-field in the optical disc recording device so that the optical disc can rotate stably.
Claims10
An optical disc recording device, comprising:
- a housing comprising a bottom hosing and a top cover;
- an optical write/read module disposed inside the housing, wherein the optical write/read module comprises an optical write/read head which moves back and forth along a Track-seeking path;
- and
- a transmission module disposed inside the housing, wherein the transmission module is suitable for spinning the optical disc rotation with respect to a rotation axis;
- wherein, the top cover comprises an inner surface and an outer surface, and the inner surface of the top cover comprises a first protrusion and a second protrusion both disposed above a track-seeking path, the first protruding being closer to the rotation axis than the second protruding, and the height of the first protrusion being lower than that of the second protrusion.
