Hello; I gave a cd to some co-workers at the state agency I use to work for. They told me that they could not load the cd into the Dell PC because the diameter of the center hole was larger than the One on the CD that I gave them. This doesn't sound right, but I was just wondering was the diameter of the center hub on a cd reader and/or cd, always the same diameter since its inception (back in 1955?)
Well i don't know about 1955 but for the last 10 years or more they have always accepted 12cm and 8cm cd's! I've never heard of a cd drive that could'nt fit a cd properly!
Originally, that may have been, but CD's as we know them were introduced to the public during the 1980's. During the 1990's the CD drive was introduced for the PC. Unless you know something I don't, I don't think the CD drive as we know it was on computers back in the 1950's. You still had data on reels and computers that required a large room.
Don't take this the wrong way but I found that pretty funny. Even the prospect of a Dell computer from 1955 or a modern Dell using antique hardware cracks me up. Either way it was only in the 70's that "Video laser disks" hit the market (they were 12" DVD's of the day, 30mins of video per side). Then in the Late 70's Phillips and Sony had prototypes of "digital audio disks", and in '79 the two companies joined forces and worked on a digital audio disk together. In '83 they went gold and you could buy them if you were hip enough. It wasn't until '85 that CD ROM's hit the market so you could do more than record music. Then in the early 90's like B said CD-R's hit the market, but it was only in about '98 I think that you ever heard of anyone burning a CD. (I remember it was a huge deal when I had my friends uncle burn me a copy of WarCraft 2, that was about '98 or 99, as the days before copyright protection). All I'm saying by this is the 1955 bit has to be off. What company would use 50 year old hardware.
