Repairing a CD RW
Dear NG,
IŽd like to ask a few questions about CD-RW drives. I better however start with a short story of how mine became out of order. The tray was not coming out completely so I decided to repair it... unfortunately I wasnŽt at a very good mood, I however managed to make the tray come out properly by doing a bit of lubrication (with vegetable oil.. I know it wasnŽt the best lubricant but I wasnŽt thinking then). Then after sometime this problem repeated, so I did something which I donŽt exactly remember but somehow the tray got stuck in the drive and could not come out anymore. I used a little force and managed to pry it out. But then I felt something was broken and that it wasnŽt able to read CDs anymore. After disassembling the drive, I realized that the optical drive had a black plastic cover that sorounds the laser diode (or laser light source, whatever that is), and it was broken and I in fact found that broken piece. I then glued it back. ... but well :) ... it cant read CDs anymore. I wonder if its already hopeless to make this CD drive work (I can of course buy a new one, but IŽd also love to learn and experiment with the mechanism of this one. It will be a good punishment for me and give me a lesson not to damage a gadget more than it is already damaged). Also, I found a website that has everything about CD-repairs and apparently it was an extract from sci.electronics.repair. But unfortunately I am unable to recall this site. If anyone knows it, IŽd be glad if he could share it with me. Many thanks. Sincerely, Jose Capco |

If anyone knows it, IŽd be glad if he could share it with me. If the black piece is just the cover over the optical pickup, that's irrelevant and the drive would work without it. However, the fact that it is broken suggests that there may indeed be other more serious problems caused when you forced the tray out. If you want to learn, go to the CD repair guide at the sites below. But probably best to just buy a new one for now. --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.

Repairing a CD RW
Maybe the piece got caught by the tray and in forcing the tray to move, it
changed the laser alignment. WT "Sam Goldwasser" wrote in message ... Jose Capco writes: Dear NG, IŽd like to ask a few questions about CD-RW drives.
