CIRCUIT OPERATIONAL DESCRIPTION

CIRCUIT OPERATIONAL DESCRIPTION

3) Loader Part

The loader which read the data of audio/video from optic disc and transfer them to MPEG
decoder can be divided into Deck total DVD assay(in a short term, Mecha) and Servo. Mecha
mounts with the optical pick-up which allows reading the signal of a disc using laser beam
and makes it operates and consists of the deck mechanism which allows loading a disc and
reading the data. Servo is a sort of circuit which allows operating the loader and recovering
the data and consists of Motor Drive IC operating the spindle, the sled, the loading motor.
