thread_title: Tray or slot-in

message: In my Computer Information Systems class we were told that there are two types of optical disks, the CD and the DVD. Now I'm reading this article and I'm like what the hell? Not that I trust my class over wikipedia. Obviously. Erik E. 02:20, 13 February 2007 (UTC)
replies: text: Well, I think the article is a reasonably good and yet concise representation of the current situation. CD and DVD are by far the most common, being the most versatile, but Blu-Ray and HD-DVD are coming up fast, and MiniDisc, while on the way out, is still viable for personal recording. Much of the bestiary you see is variations on a theme, while a lot of it is either vaporware or experimental, or just plain never worked out (DataPlay, anyone?).

thread_title: Who invented the optical disc

message: I do not think that classifications in generations explains the readers much. why not simply write CD, DVD etc. This tendency to classify products into generations seems to be a typical trait of the English Wikipedia which is fortunately not so strong in other Wikipedias.

message: Down where it talks about the blu-ray read speed it says 12x but the referenced article only talks about 6x.  Could someone who knows more about this either fix it or explain why it's that way?

message: "The optical disc was invented in 1958."
Uhhh, no. Gilbert King was leading development of a read-only optical disk system at International Telemeter starting in 1953. They made numerous devices during development. After moving to IBM in 1958 he delivered a real working system to the Air Force in 1959, and by "working system" I mean a complete online data system with computer, disk, etc. My guess is that there were even earlier attempts, but I can't demonstrate that. What I can demonstrate is...
G.W. King, G.W. Brown and L.N.  Ridenour, "Photographic Techniques for Information Storage", Proceedings of the IRE', Volume 41 Issue 10 (October 1953), pp. 1421-1428
Ridenour, BTW, was one of the co-developers of the SCR-584.

replies: text: Additionally, why does the current version of the article tell me the optical disc was invented in 1958, yet it shows me a picture of an "analog optical disc" from 1935? These conflicting elements cause confusion. The orgel disc should not be a part of this article.173.28.60.82 (talk) 08:45, 24 April 2011 (UTC)
thread_title:  History? 

message: This says that flash memory is more reliable. Flash memory only lasts about 10 years - hardly reliable. Optical discs can last up to 100 years or more (for high-end brands, eg. Taiyo Yuden or MAM-A).  —Preceding unsigned comment added by 174.111.242.33 (talk) 21:53, 26 October 2010 (UTC)
thread_title:  Flash memory more reliable? 

message: A long time ago (early to mid 90's?) I recall seeing a bit in a magazine (Popular Science?) about a business card size optical "disc" that didn't spin, but was read without moving parts and the surface looked like and was shiny just like CD's and DVD's. In fact, were a CD or DVD cut precisely and cleanly into a rectangle (obviously smaller than an actual business card as the central hub would be part of such a disection) it would look just like what I saw. Google searches turned up nothing resembling this and it wasn't a bootable business card or Shaped Compact Disc. Maybe I'm just remembering this incorrectly and/or didn't understand what it was I was looking at, but should this have existed (Is solid state optical media even possible or is spinning a necessity?), would it warrant  a mention?  —Preceding unsigned comment added by 4.254.86.87 (talk) 01:02, 14 February 2011 (UTC)
