Capacitance Electronic Disc Technology

Unlike optical discs, CED uses a physical stylus that reads microscopic variations in electrical capacitance stored in conductive grooves on the disc surface.

Fun Facts:

RCA invested $580 million over 17 years developing CED
Discs rotated at exactly 450 RPM
Each disc could hold ~60 minutes per side
The stylus was thinner than a human hair
CED players were discontinued after just 4 years

1983 Format Comparison:

Format	Capacity	Price	Picture Quality
CED	60min/side	$200-400	Good
VHS	120min	$300-800	Fair
LaserDisc	60min/side	$700+	Excellent
