Hello to all,
this question might fit into the analog source forum as well, as Nakamichi
was famous for it´s tape decks. But the machines mentioned
are the OMS-5 and OMS-7 CD-Players, mark one and mark two, introduced first around 1984.
These players used a belt for driving the laser head.
I have never seen this design in other CD-Players.
The belt detoriates and even though there are
still replacements available,I want to replace the worn belt with gears.
I measured everything and this seems doable.
But for milling the gear -that also drives another gear that will not be replaced -
it is not clear whether Nakamichi used the metric system or inch.
It could be a module (or modulus) of 0.4 in metric, in inch it could be 60dp.
(I do not know whether it is written 60dp or dp60)
Both are very close as Dp60 is a module of 0.433.
So bevor starting the adventure of having gear milled, it should be good
to know whether inch or metric are be the base for the design.
Does anyone definately know which norm Nakamichi´s engineers used?
I assume they made no difference if it was tape decks or CD Players.
So maybe some expert on Nak tapedecks might know the answer…
All the best,
Salar
