Wearnes VCD CD MP3 Player - Laser Beam Focusing Coil

This is the laser beam focusing assembly. This focus the laser beam into a very fine beam for reading the information burned into the cd.

The focusing lens is plastic.

The left picture shows the focusing assembly part, note the copper wire coils and the small but strong magnets which together moved the lens up/down and sideways as the electronics controlled the current through the coil.
