"Dear Zilog Jones, Do you really think that your contribution

"There is a hole in the centre of the disc, usually used by a some form of clamp or clip device within the player to hold it in place and allow it to be rotated by a motor. The diameter of the hole is 15mm - coincidentally the same size as a Dutch 10 cent coin."

will add to the value of the CD article? Specifically, your remark regarding the fact that the diameter is 15 mm, which is the size of a Dutch coin. Why is this so important? Each and every size has been used somewhere, so it is not difficult to relate anything with anything. Is there something of historical relevance in this fact? If so, please add, otherwise this 'fact' can better be removed. Dsc 16:43, 13 Jun 2005 (UTC)"

Someone mentioned earlier in the CD discussion page that the hole was based on the size of a dutch coin, but wasn't sure which one. And as you may know, Philips are a dutch company! AFAIK they had a lot of input with the design of the disc, especially since Sony and other Japanese companies were originally planning on using 30cm optical discs for audio. From what I know it was Philips who put forward the 12cm format, so it's likely they designed it.

Also, there was no mention of the hole in the centre before - the dimensions of it, or its purpose. I don't know if there truly is a relationship between the hole and a dutch 10 cent coin, but it's possible. --Zilog Jones 17:53, 15 Jun 2005 (UTC)

The diameter of the center hole is irrelevant for Wikipedia. It has no effect on the playing time or other key parameters of the CD and DVD. The possible relationship with the Dutch coin is coincidental. In the same way as you did, I could write that CD's outer diameter, 12 cm, is the same as that of the Heineken beermat (coaster). And as you may know, Philips and Heineken are Dutch companies! So my conclusion, let us stop listing trivialties in wikipedia, so pls remove both your contributions regarding the center hole and the dutch coin. Dsc 05:46, 16 Jun 2005 (UTC)

OK, but the diameter and purpose of the hole is still relevant, just like the diameter of the disc itself and other physical parameters which were already mentioned. --Zilog Jones 20:55, 20 Jun 2005 (UTC)

OK. Could you explain why the hole diameter is relevant for wikipedia. As said the playing time is not affected by the choice of the diameter. The playing time (and thus capacity) is determined by the inner diameter program area, which equals 50 mm (more than three times larger than the inner hole diamter, 15 mm).

Hello, I want to mention that the size of the (pre Euro) Dutch 10 cent coin and the size of the CD hole is NOT coincidence. It is a fact that Philips used this size. And yes, I think it is important for Wikipedia, because it is historical, besides, it is an intresting fact, that alone is an reason to mention. Marius

Hello also, I would wish to add my sincere appreciation for the revealing insight of the correlation between the 15 mm CD center hole and the pre-Euro Dutch 10 cent coin. I have looked extensively for reasoning behind the 15mm CD hole size with no avail - until now. So, Thank You Zilog Jones for this truly unique and valuable 15mm CD hole size reasoning info.

[edit] DualDisc FAC

Hey Dsc. Thanks for all your feedback on the article. The nomination for Featured Article failed the first time around, but I have re-submitted it as an FAC. I was wondering if you'd consider supporting it? Cheers! --K1vsr (talk) 15:45, August 17, 2005 (UTC)

[edit] The matter of Dr. James R. Russell's article

Hi there. I wrote Professor/Dr. James R. Russell's article as he is indeed a world known scholar in his field and very notable. I checked that his colleague, Dr. Wheeler Thackston had an article, which he has since 2004. They are both in the same department at Harvard, and on comparable par. Dr. Russell's opus "Zoroastrianism in Armenia" is a major work published by Harvard University amongst other works of his. The article is not a vanity article and Dr. Russell who occupies the Mashtots Chair in Armenian Studies, at Harvard University, which is a very prestigious chair, is more than noteworthy. As much as Dr. Wheeler Thackston is. Dr. Russell's article is James R. Russell. Thanks for your attention. Please remove the warning from the article. Thanks. --- (Bob) Wikiklrsc 20:24, 27 February 2006 (UTC)

Hi Dsc, I noticed you reverted me on James R. Russell with the edit comment "rm vandalism". My edit most certainly was not vandalism. I looked at your comments and reviewed the article and agreed with Wikiklrsc that the banner was not needed. I think it would be better to discuss this on the talk page rather than getting into any kind of dispute. Perhaps you could expand on why you feel this is a vanity page there?
