I've seen this problem with car cd players and portables - pretty much anything that gets bounced around. Any solution for this besides that cheesily-named d-skin ("duh skin")?
My friend says turn the laser up ( by turning the pot down).
I would question whether any but the multilayer machines even have a vertical lens adjustment let alone active control over it. most just have a spring holding it all the way up, no?
He says the laser is moving in closer to the disk to get a better reflection... again, I doubt it. I can see that perhaps a machine would be built so that reading problems result in a panic behavior rapid refocusing - but I don't think they're built that way - CD players or regular dvds.
Then again, I don't know where to find cd lens guide design documents.
Thanks for any info... please state credentials or reference documents.
