Inspired by Bichi’s pictures here and here I decided to pull apart a high vibration 16W1P drive to see what I could do. It had the later spindle motor, like the November model, and just the two spindle bracket suspension screws, like in bichi’s picture of the September model.
I ended up fitting a ruffly 0.5mm thick pressed washer under the head of each of the two mounting screws. The washers were a larger size than the head of the screw and covered the entire top of the silicone mount.
The drive now has noticeably less vibration when used at the 16x RPM, however what I wasn’t expecting was a noticeable improvement in the drives quality. I can only put it down to not having so much vibration, with the stiffer spindle suspension, allowing the drive to burn and/or read better. The leadin time seems to be slightly faster by a few seconds as well, but this may have just been the discs I have tried so far, or perhaps the drive can lock on to the media better, with less vibration.
I’ve attached the first two burns after fitting the washers. The MCC004 only had 128 PIF errors before the slight defect at the outside of the disc, which is amazing for this batch of media.
Note: Please don’t try this at home :p, unless you are very competent at carrying out this sort of thing. There are things that can be broken and things that shouldn’t be touched inside an optical drive and of course, you will void your warranty. You have been warned.
