And what would those details be?

Type of magnets in the arm-assembly, types of voice coils, current,
electronic behind the whole problem, etc?

That is about right. I am interested in the magnetic circuit. I believe
that it is in the form of a transformer "E-I" core with permanent
magnets. The coil slides back and forth. Values for the magnetic field
the coil sees is also of interest.

Best look into a datasheet or design manual for a moving coild
driver then. Several companies are making them.

Permanent magnet is always Neodymium... About the values of currents and
fields, I don't know nothing...

Like the other guy said - check out the datasheets of driver manufacturers
(driver as a chip, not software driver)...

Ask in the sci.electronics.* groups, like basics or design.
