CD players are often installed into home stereo systems, car audio systems, and personal computers; they are also manufactured as portable devices. Some technology supports other formats, in addition to CDs, such as DVD, CD-ROMs with audio files, and video CDs. DJs often use pitchable CD players, which have an adjustable playback sampling rate; however, the same technique can be exploited with cheaper filters used in-line with MP3 players.

Interface

Compared to digital audio players, which have screens, CD players are most often less user-friendly, because tracks are numbered rather than displayed with text. However, CD-Text has overcome these aforementioned limitations; so text is displayed with the CD player software available on computers and modern CD players. Tray numbers on CD changers are often confusing for those who want to select individual tracks. MP3 players, which list tracks in alphabetical order, however, are easier to use.

Individuals once memorized album track numbers with vinyl records, as with CDs in the present-day.

CD changer

A CD changer holds multiple Compact Discs, usually in a cartridge, and allows the user to access (or play) any of them, one at a time. CD changers are commonly found in home cinema systems, cars, and less often in computer equipment.

Prior art

Prior to real CD changers being introduced, an attempt was made to copy the double cassette players found in many audio systems. As a result, CD players with two separate, fully functional CD players were 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 CDs were not commercially available. Therefore, the shift to changers was swift, removing the need for duplicate parts.

Main types of CD changers

External cartridge

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