Wrong. One motor. The head moves with something called a voice coil. It's completely solid state. Open up a hard drive and watch it move back and forth while it's working. Of course this isn't good for the hard drive, but it looks basically instant to the naked eye. Very cool.
- bullen 5y agook, I guess "moving part" would have been more precise, still the argument holds: that coil breaks.
- beervirus 5y agoProbably splitting hairs, but I’d still call it a motor. It transforms electric current into physical motion.
- agumonkey 5y agotrue but the structure is simpler than the main disc motor
