Top-loading was adopted on various equipment designs such as mini systems and portable CD players, but among stereo component CD players, only a handful of top-loading models have been made. Examples include 's D-500 and D-500X series players and 's DP-S1, both launched in 1993. Top-loading is also common in players intended for broadcast and live sound "DJ" use, such as Technics' SL-P50 (1984-1985) and Technics SL-P1200 (1986-1992). They more closely mimic the physical arrangement and ergonomics of record turntables used in those applications.
The process of playing an audio CD, touted as a digital audio storage medium, starts with the plastic polycarbonate compact disc, an analogue medium that contains the digitally encoded data. The disc is placed in a tray which either opens up (as with portable CD players) or slides out (the norm with in-home CD players, computer disc drives and game consoles). In some systems, the user slides the disc into a slot (e.g., car stereo CD players). Once the disc is loaded into the tray, the data is read out by a mechanism that scans the spiral data track using a beam. An electric motor spins the disc. The tracking control is done by analogue servoamplifiers and then the high frequency analogue signal read from the disc is digitized, processed and decoded into analogue audio and digital control data which is used by the player to position the playback mechanism on the correct track, do the skip and seek functions and display track, time, index and, on newer players in the 2010s, display title and artist information on a display placed in the front panel.

This can occur if you burned an audio CD on CD-RW (compact disc, rewriteable) media, and you are trying to play it in a car or stereo CD player. CD-RWs are 70% less reflective than normal CDs, and many stereo and car CD player lasers are not powerful enough to read them.
To work around this issue, burn audio CDs only to high-quality, brand name CD-R (compact disc, recordable) media.
