| 摘要 |
The invention relates to an optical disk drive, which can be built very small. In order to solve cooling problems and collecting light reflected from the disk with maximum efficiency an optical disk drive is proposed comprising:-a laser diode for generating a laser beam, said laser diode being located at a fixed position in the drive,-an objective for focussing said laser beam on an optical disk,-a light guide for guiding said laser beam from said laser diode to said objective,-a detector for detecting light reflected from the optical disk, and-a movable swing arm for carrying said objective and said detector, said detector being arranged close to said objective such that the light reflected from the optical disk through said objective is detected.
