Audio, what an amazing hobby.
Talking about CD vibrations, flutter and scattered light seems to be assessing analog diseases to a non analog entity.
How can it be possible?
Never heard of a Tesla losing engine power due to a unappropriate timing belt installation.
As Kosst pointed out, we should retrieve exactly the same data from every disc reader.
If this data reading system would be so unefficient, how can we successfully and consistently run programs and data from it?
The rationale behind this school of thinking is if we miss a single bit or data in the numerical string of data of an audio file, it will be audible.
It makes sense but an audio file is no different than any other numerical file, especially a program file.
Do you think that a reading error will not make a program fail ?
I would tend to believe that whether it runs or it crashes.
About reading problems concerning the laser,
first, if vibrations and all were a problem, this system of data retrieving would not work at all for computers,
second, compared to speed of light, the speed of non desirable movements of disk are kind of neglectible ...
When we know, we can prove it and explain it rigthly.
I do not pretend to know, I only pretend to be ... amazed!
