I would first attempt what Laffin has described above.
If that fails, I have much experience in disassembling drives, cleaning them, and putting them back together.
First thing is, take the case cover off. Blow completely with compressed air (a can from your local retailer will work great), if your drive has no reading problems/writing problems, skip over cleaning the lense.
Next get a small spray can of WHITE LITHIUM GREASE. The can will come with a pinpoint spray attachment. Lubricate SPARINGLY, the gear, and the slide for the drive tray. This should eliminate the slowing down of the drive tray. It sounds as if something has become lodged in the gear, could be lint, trash, paper, open and close the drive (mechanically) and inspect it's travel, and watch the gear for small obstructions as you do so. Remove with tweasers any foreign object that you can visualise. If you do not feel comfortable with spraying the lithium grease (it is very poisonious) simply use a cuetip with a small dab of petroleum jelly, this will work just as well, it just does not last as long.
Last, post back and let us know how it works out.
