Will it read prerecorded MD's?
In my experience, there are 2 things that can fix an MD player that will
read prerecorded MD's and not recordable ones:
- MO Focus Bias
- Laser Power (or MO Laser Read Power if it's separate)
I always start with MO Focus Bias. Adjusting it will fix MD players
that aren't too worn out. If MO Focus Bias doesn't correct it at all,
then I move on to Laser Power and increase it JUST A LITTLE until it
will read an MD. If neither control will result in the ability to read
an MD, then usually that means the optical block is just hopelessly worn
out and needs replacement.
I'm not sure what other "head alignment" is possible. If it's just
having difficulty finding the TOC, then it probably just has a bad
end-of-travel microswitch.
