Talk:CD player

message: I'm having problems refering to the proper sources of the data. I'm basing this article in the redbook standard and a few service manuals of CD players. The standard is not freely available and I think the manuals are copyrighted so I should add them anyways?
Also, part of this has a different language publication as a source, I don't know if that is going to represent a problem.

thread_title: Added (adding actually) How it works

message: This part needs clarification, citation or discussion "The radial mechanism works best for CD-ROMs, though, as the speed of the disc increases". I think that's false, the swing arm mechanism provides higher seek speed than a linear movement based on the rotation of a motor.
::The problem isn't seek speed - it's that a swing-arm mech conventionally only has a single actuator for both seek and tracking, and it's carrying the substantial moving mass of the whole optical pickup assembly.  As the disc speed increases, the required bandwidth of the tracking error signal also increases, and moving the whole pickup at those frequencies would require excessive power.  The linear mechs have this feedback split into low frequency (sled) and high frequency (lens positioner) components anyway, so it's a lot more tractable.
::Another consideration (although less important) is that single beam pickups have a wider capture range for both focus and tracking and produce a correspondingly smaller error signal - this can obviously be addressed by using more servo gain, but servos with high gain and wide bandwidth (needed because of the higher disc speed) tend to be more difficult to stabilize. 116.76.111.53 (talk) 03:36, 4 April 2014 (UTC)

message: "If proper care is taken, a CD can be played indefinitely without any loss in audio quality."
Aside from the lack of citation (as far as I can tell), I once heard that CDs have a shelf life of around 50 years... might be worth investigating
In fact, this entire page seems to be lacking citations Hydroksyde 23:41, 21 June 2006 (UTC)
replies: text: This is true (not necesarily 50 years, the time depends on the brand of the media). But the article refers to the fact that a CD does not worn like an LP or a cassette, because of the lack of friction of the system itself.--Lenilucho 01:19, 22 June 2006 (UTC)
replies: text:  Perhaps, but that revert was unnecessary, as I didn't change any information, just added the citation/unreferenced templates. Just even if something is true, it *still* needs references, see Wikipedia:Verifiability. Hydroksyde 06:39, 22 June 2006 (UTC)
replies: text:  Ok, I added information. Do you think the "citation needed" is still necesary?--Lenilucho 03:09, 23 June 2006 (UTC)
replies: text:  You've missed my point entirely. You can't just write things down off the top of your head. You need to find any information you add in a reputable publication (eg a book, or a reputable newspaper), that can be verified, and reference this information appropriately.

replies: text:  Ok, I get it. I have no idea where to find such information. May be on Sony/Philips/TDK or similar websites? --Lenilucho 06:25, 25 June 2006 (UTC)
thread_title:  CD Life span 

message: I have made several copyedits, which hopefully make the article more readable. I removed much of language of the kind (exaggerated here for effect): CD players are cool, but they, like, suck compared to other technologies, like DVDs which have scrolling interface user-friendly text.
In future, please restrict the content to objective descriptions, and refrain from reviewing the technology. 
If the copy-edit tag remains, I might return later to tamper with the rest of the article. Rintrah 12:50, 20 October 2006 (UTC)
replies: text: I've gone over and done the copyediting I can do, but the interface section still needs work. It doesn't actually describe the interface of a CD player, but rather compares it to the interface of an MP3 player. I also removed the following: 
"For the home consumer, some options exist:
Sony XL1 (or XL1B2) - a Windows Media Center based disc changer, for local (MCE) use only
PowerFile
For larger enterprise solutions, the following are available:
PowerFile (A3 and PSA models)
JVC
Pionneer (DRM series)
PoINT Software (www.pointsoft.de) - develops software to manage CD/DVD changers in corporate environments (supplements enterprise features)"
Wikipedia is not a product quide.
I will remove the copyedit tags and add a expand tag to the interface section if I can't find any info to add to it. Natalie 17:57, 22 November 2006 (UTC)
thread_title:  Copyedits and article tone 

message: Removed the following from "User 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."
Uncited POV. If readding, please provide citations. Natalie 19:15, 22 November 2006 (UTC)

message: Article says "the first generation iPod can hold an equivalent of 5 discs with a 128k sample rate for each song". But the first generation iPods are 5GB, which is more than 5 CDs or 5*700MB=3500MB, and that's lossless, not 128kbps. At 128kbps it should store >60 CDs. Shawnc 04:20, 9 December 2006 (UTC)

message: I've added some info on the mega-disc type of CD changers. Some info on impact of Hard disk based MP3 player on the mega-disc changer market would be useful. Do they still make this type of changer? Also their have been some combo CD players/HD-based mp3 player systems on the market at various times that allowed CD's inserted into them to be ripped to an internal HD drive on the unit. They where offered as a alternative to  using a computer for this task.  These units where designed exclusively for playing digital music through one's stereo system and where not very portable. If anyone has any info on this type of CD/MP3 combo player then please add it. --Cab88 08:27, 5 February 2007 (UTC)

message: The last part about computer-based CD changers compares them with hard drives. Yet at that time when they existed (stated to be circa 1990), no CDs were Read-Write like a hard drive — CD's were read only. The R/W technology for CD's didn’t exist yet.
1) So what was the purpose of the changers, since it clearly wasn’t to replace hard drive capacity? Like a huge ROM? This is not clear at all.
2) Perhaps there shouldn’t be any comparison with hard drives.
3) The purpose of the changers should be given in the article. JWmpls (talk) 01:46, 31 October 2018 (UTC)
