Planetary compact disc recorder

The invention relates to the field of computers, in particular to a planetary compact disc recorder. Four drive assemblies in the planetary compact disc recorder are evenly distributed on a rotary disc and sequentially drive sun gears and planetary gears through speed regulating drive motors, and the sun gears and the planetary gears drive compact discs on compact disc clamp shaft heads to rotate at a constant speed so as to complete compact disc recording. Linear servo stepping motors rotate to drive helical lead screws to move upwards, then the helical lead screws drive hinge joint seats connected onto the helical lead screws in a sleeving mode to move upwards, and laser heads complete the whole recording work from inner circles to outer circles and complete simultaneous recording of a plurality of compact discs due to accurate motions of the linear servo stepping motors. Track seeking mechanism assemblies are switched to other drive assemblies in position each time cam indexing unit and a main power motor rotate at 90 degrees, the compact discs completely recorded on the drive assemblies are replaced while recording, the time for arranging compact discs to be recorded is not needed, and the effect of simultaneously recording a plurality of compact discs is really achieved.
