Sorry - slip of the keyboard. The Denon, Sony, and NADs are not, of course,fritz wrote:
You don't understand what a spindle motor does, obviously.
It just spins the disk, it has nothing to do with the tracking of the
laser, which I
have already explained. The spindle motor has feedback to spin the CD
at
the right speed, usually with Hall effect sensors. The coarse
tracking is controlled
by a separate motor with position feedback, and fine tracking is
controlled with
a 'voice coil' suspension connected to the laser lens.
Dude, I think I know eactly what a spindle motor does - I fix Denon,
Sony, and Nad ones every week and have don for decades. Also DVD and
DVD/CD-ROM/RWs.
