[[Sony]] released its [[CDP-101]] CD player<ref>{{cite web | url = http://www.cedmagic.com/history/sony-dp-101.html | title = CDP-101 The first Compact Disc Audio CD Player from 1982 | access-date = 2007-02-05 | year = 2007 }}{{Dead link|date=June 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> in 1982 with a slide-out tray design for the CD. As it was easy to manufacture and to use, most CD player manufacturers stayed with the tray style ever since.<ref>{{cite web | url = http://www.niji.or.jp/home/k-nisi/pd-t09-mecha2.jpg | title = Pioneer Stable Platter Mechanism | language = ja}}</ref><ref>{{cite web | url = http://www.audioscope.net/images/pioneerpd97002.jpg | title = Pioneer Stable Platter Mechanism }}</ref> The tray mechanism is also used in many modern [[desktop computer]] [[computer case|case]]s, as well as the [[Philips CD-i]], [[PlayStation 2]], [[Xbox (console)|Xbox]] and [[Xbox 360]]. However, there have been some notable exceptions to this common CD tray design.

===Vertical loading===
During the launch of the first prototype ''Goronta'' CD player<ref>{{cite web|url=http://www.sony.net/Fun/SH/1-20/h5.html |title=Sony History |access-date=2007-02-05 |year=2007 |archive-url=https://web.archive.org/web/20061130231112/http://www.sony.net/Fun/SH/1-20/h5.html |archive-date=2006-11-30 |url-status=dead }}</ref> by [[Sony]] at the Japanese Audio Fair in 1982, Sony showcased the vertical loading design. Although the Sony prototype design was never put into volume production, the concept was for a time adopted for production by a number of early Japanese CD player manufacturers, including [[Luxman|Alpine/Luxman]], [[Panasonic Corporation|Matsushita]] under the [[Technics (brand)|Technics]] brand, [[Kenwood Corporation|Kenwood]] and [[Toshiba|Toshiba/Aurex]]. For the early vertical loading players, Alpine sourced their AD-7100 player designs for Luxman,<ref>{{cite web | url = http://www.thevintageknob.org/DAD/DX104/DX104.html | title = Luxman DX-104 CD Player | access-date = 2007-02-17 | year = 2007}}</ref> Kenwood and Toshiba (using their Aurex brand). Kenwood added their ''Sigma Drive'' outputs to this design as a modification. A picture of this early design can be seen on the Panasonic Web site.<ref>{{cite web | url = http://panasonic.net/history/corporate/products/inp1982.html | title = Panasonic History - Innovative Products - 1982 - CD Player | access-date = 2007-02-05 | year = 2007 | archive-url = https://web.archive.org/web/20081006075040/http://panasonic.net/history/corporate/products/inp1982.html | archive-date = 2008-10-06 | url-status = dead }}</ref> The vertical loading is similar the one common in [[cassette deck]]s, where the holder opens, and disc is dropped to it. The holder is closed manually, by motor after pressing a button, or completely automatically. Some CD players combine vertical loading with slot loading due to the disc being drawn further into the disc holder as it closes.

===Top loading===

In 1983, Philips, at the US and European launch of the CD format, showcased the first top-loading CD tray designs with their CD100 CD player.<ref>[http://www.marantzphilips.nl/philips_cd100_first_cdplayer/ Philips CD100 Player] - Marantz-Philips Nederlands website</ref><ref>[http://www.research.philips.com/technologies/projects/cd/introduction.html The history of the CD - The introduction], Philips Research.</ref> (Philips audio products were sold as [[Magnavox]] in the US at the time.) The design had a clamp on the lid which meant the user had to close this over the CD when it was placed inside the machine. Later, [[Meridian Audio, Ltd.|Meridian]] introduced their MCD high end CD player,<ref>{{cite web|url=http://www.meridian-audio.com/p_cd_history.htm |title=Meridian CD History |access-date=2007-02-05 |year=2007 |archive-url=https://web.archive.org/web/20070204043147/http://www.meridian-audio.com/p_cd_history.htm |archive-date=2007-02-04 |url-status=dead }}</ref> with Meridian electronics in the Philips CD100 chassis.

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 [[Luxman]]'s D-500 and D-500X series<ref>{{cite web | url = http://k-nisi.hp.infoseek.co.jp/d-500-xs.html | title = Luxman D-500X (in Japanese) | access-date = 2007-02-05 | year = 2007 | archive-url = https://web.archive.org/web/20070717004455/http://k-nisi.hp.infoseek.co.jp/d-500-xs.html | archive-date = 2007-07-17 | url-status = dead }}</ref> players and [[Denon]]'s DP-S1,<ref>{{cite web | url = http://denon.jp/museum/products/dps1.html | title = Denon Museum - Model History - 1993 - DP-S1 (in Japanese) | access-date = 2007-02-05 | year = 2007 | archive-url = https://web.archive.org/web/20070204103139/http://denon.jp/museum/products/dps1.html | archive-date = 2007-02-04 | url-status = dead }}</ref> 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 top-loading disc tray design is also used in most [[fifth generation of video game consoles|fifth-generation]] [[video game]] [[video game console|console]]s ([[PlayStation (console)|PlayStation]], [[Sega Saturn|Saturn]], [[3DO Interactive Multiplayer]]), as well as the [[Dreamcast]], [[GameCube]], and [[Wii Mini]].

===Tray loading with sliding mechanism===
{{unreferenced section|date=January 2014}}
The Philips CD303 of 1983-1984 was the first player to adopt tray loading with a sliding play mechanism. Basically, as the tray came out to collect the CD, the entire player's transport system also came out as one unit. The [[Meridian Audio, Ltd.|Meridian]]s 200 and 203 players were of this type. They were also the first to use a design in which the audio electronics were in a separate enclosure from the CD drive and pickup mechanism. A similar mechanism is used in slim optical disc drives (also known as slim internal DVD drive, optical drive or DVD burner), which were once commonly used in laptop computers.

===Slot loading===
{{unreferenced section|date=January 2014}}
Slot loading is the preferred loading mechanism for car audio players. There is no tray that pops out, and a motor is used to assist disc insertion and removal. Some slot-loading mechanisms and changers can load and play back [[Mini CD]]s without the need of an adapter (such as the original [[Wii]] model's standard-sized disc slot being capable of accepting smaller [[GameCube Game Disc]]s) but they may work with limited functionality (a disc changer with a Mini CD inserted will refuse to operate until such disc is removed, for example).
[[Shaped Compact Disc|Non-circular CDs]] cannot be used on such loaders because they cannot handle non-circular discs. When inserted, such discs may become stuck and damage the mechanism. It is also used on some laptop computers, the [[PlayStation 3 models|original and slim]] [[PlayStation 3]], the Wii's original model and its Family Edition and most [[eighth generation of video game consoles|eighth-generation]] video game consoles (the [[Wii U]], [[PlayStation 4]] and [[Xbox One]]), as well as the [[ninth generation of video game consoles|ninth-generation]] [[PlayStation 5]] and [[Xbox Series X]].
