Got an old pc with no dvd drive in it? Why not mod it’s CD rom drive to play DVD’s this weekend?

Laser Head Adjustments:
The track pitch of CDs is 1.6 microns, and the track pitch of DVDs is only 0.8 microns. The minimum length of track pits of CDs is 0.843mm, and the minimum length of track pits of DVDs is 0.293mm. That’s why DVD discs can store much more data in the size of a CD.
Pinpointing this situation, we need to adjust the laser head so it can read discs with smaller track pitchs and shorter track pits. Open up the CD-ROM drive, do you see a lens on the rail? That’s the laser head. On the side of the laser head, there’s a screw you can adjust.
