I thought CDs were usually described as being 5-inch diameter?
I certainly hope not, Phil!
I have a CD-R (the actual disc), and inside the case is a list of Features
(e.g. 650MB capacity, etc.) and also "120mm outer diameter, 15mm inner
diameter" and "1.2mm thickness". In addition, it says "1.5m/sec linear
velocity" and to cap it all off, "Operates in +5ºC to +55ºC".
Excellent stuff!

That is correct; the CD(ROM/RW) etc. was designed as 120 mm. Occasionally
you do see it described as 5", including on a leaflet sent to me by WH Smith
some time ago. I never did get round to writing
to complain. - Chris
