| These early CD Rom drives used a plastic carrier to hold the CD, the whole thing being inserted and ejected from the CD Rom drive like a cartridge. | These early CD Rom drives used a plastic carrier to hold the CD, the whole thing being inserted and ejected from the CD Rom drive like a cartridge. |
| The drive contains three motors, spin motor, head positioning motor and eject motor. All appear to be 5V motors. The spin motor is a direct drive of the CD, the head positioner has a hall-effect rotary encoder, gear chain and rack and pinion drive head slide. The eject motor uses a worm screw that drives gears and cams to actuate the eject mechanism. The spin and head motors can be easily extracted. Using the head positioning mechanism and rotary encoder feedback would be possibly, but difficult. The whole eject actuator could be separated out to use as a, not very compact, servo. | The drive contains three motors, spin motor, head positioning motor and eject motor.
