Optical disc drive having pickup integrated with disc insertion tray
View Patent ↗A disc drive including a tray, a housing configured to receive the tray, a pickup device installed on the tray, and a main circuit board installed on the tray and connected to the pickup device.
1. A disc drive, the disc drive comprising:
a tray;
a housing configured to receive the tray;
a pickup device installed on the tray;
a spindle motor installed on the tray;
a main circuit board including a front-end system in the disc drive with a radio frequency amplifier and a servo circuit, the main circuit board installed on the tray and connected to the pickup device;
a connector installed in the housing that is directly connected to the main circuit board via a cable having a fixed portion facing the housing and a moveable portion that is moveable in response to movement of the tray, the connector configured to connect the disc drive to an external apparatus;
an exposed cable that directly connects the main circuit board installed on the tray to the spindle motor installed on the tray;
guide shafts installed on the tray and along which the pickup device reciprocates;
two support posts, which are integrally formed with the tray and project from opposite inner surfaces of the tray, configured to support a first of the guide shafts; and
two additional support posts, which are integrally formed with the tray and project from the opposite inner surfaces of the tray, configured to support a second of the guide shafts,
wherein the fixed portion and the moveable portion of the cable are disposed so as not to be in parallel with each other for reducing interference between the signals transmitted by the signal lines in the fixed portion and the signals transmitted by the signal lines in the moveable portion.
2. The disc drive of claim 1 , wherein a moving device configured to reciprocate the pickup device is installed on the tray.
3. The disc drive of claim 1 , wherein a rotation axis supporting portion of the spindle motor is fixed directly to the tray.
4. An electronic device, the electronic device comprising the disc drive of claim 1 .
5. The electronic device of claim 4 , wherein the electronic device is one of a portable game console, a portable/personal multimedia player (PMP), a portable lap-top PC, a desktop PC, a high definition television (HDTV), an optical disc player, and an optical disc recorder.
6. A disc drive comprising:
a tray;
a housing comprising a base and a cover, which are configured to receive the tray;
a pickup device installed on the tray;
a spindle motor installed on the tray;
a main circuit board including a front-end system in the disc drive with a radio frequency amplifier and a servo circuit, the main circuit board installed on the tray and connected to the pickup device;
a connector installed in the housing that is directly connected to the main circuit board via a cable having a fixed portion facing the housing and a moveable portion that is moveable in response to movement of the tray, the connector configured to connect the disc drive to an external apparatus;
an exposed cable that directly connects the main circuit board installed on the tray to the spindle motor installed on the tray;
guide shafts configured to be installed on the tray and along which the pickup device reciprocates;
two support posts, which are integrally formed with the tray and project from opposite inner surfaces of the tray, configured to support a first of the guide shafts; and
two additional support posts, which are integrally formed with the tray and project from the opposite inner surfaces of the tray, configured to support a second of the guide shafts,
wherein the fixed portion and the moveable portion of the cable are disposed so as not to be in parallel with each other for reducing interference between the signals transmitted by the signal lines in the fixed portion and the signals transmitted by the signal lines in the moveable portion.
7. The disc drive of claim 6 , wherein the connector is disposed at one end of the housing.
8. The disc drive of claim 6 , wherein a rotation axis supporting portion of the spindle motor is fixed directly to the tray.
9. An electronic device, the electronic device comprising the disc drive of claim 6 .
10. The electronic device of claim 9 , wherein the electronic device is one of a portable game console, a portable/personal multimedia player (PMP), a portable lap-top PC, a desktop PC, a high definition television (HDTV), an optical disc player, and an optical disc recorder.
