Prior art

Prior to real CD changers being introduced an attempt was made to copy the double cassette players found in many audio systems; CD players with two separate, fully functional CD players was made. Double cassette decks were never replaced with cassette changer, mainly because a double cassette deck could copy from one cassette to another. Double CD decks on the other hand did not have this copy functionality, since recordable CD’s was not invented, and thus the shift to changers was swift, removing the need for duplicate parts.

Main types of CD changers

External cartridge

External cartridge for 6 CDs installed in the boot of a car

External cartridge CD changers have one or more cartridges that the user loads with typically 5 to 10 CDs and then inserts into the CD changer. The CD changer can then remove one CD at a time for playing. This type of player is convienent because the user typically owns at least two cartridges and therefore can load a second one to quickly switch with the first one.

Carousel

Carousel for 3 CDs

A carousel type CD changer consists of a circular platter that holds three to seven CDs. The carousel ejects from the CD changer for the user to load CDs on to it. Once back inside, the CD changer can rotate the carousel to access all the CDs. Most carousel CD changers will allow the user to rotate the carousel while open and change (say) all three CDs if no CDs are currently playing, or to eject the carousel while one CD is playing to change (say) the two additional CDs.
