If it is one you can feel with your finger or see with your eyed and it is not the circular ring near the center hole, it is a fault, a blemish, a production error.

First consider triangles ACD and BCD. They share a common base, CD, and their height is the distance between the parallel lines AB and CD. Consequently, area(ACD) = area(BCD) . . . . . . . . eqn 1 But ACD = AOD + OCD and BCD = BOC + OCD So area(ACD) = area(AOD) + area(OCD) and area(BCD) = area(BOC) + area(OCD) Substituting in eqn 1, area(AOD) + area(OCD) = area(BOC) + area(OCD) area(AOD) = area(BOC)
== == 1) Draw a line segment AB of 5 units 2) Draw the perpendicular bisector CD of AB such that Cd meerts AB at C. 3) Mark off CE = 2 units on CD 4) Draw the straight line segments AE & BE. ABE is your triangle. Its base (AB) = 5 and height (CE) = 2, so its area = [base x ht] / 2 = 5 sq units
pi x 12 (diammeter of the CD) = 37.6991118 (the circumference of the CD)

After MUCH research looking for the answer to this myself, I have found that the parts are called either CD hubs or CD spiders. They are the "bump" that fits into the center hole of the CD and holds it to another surface when you are not using a case.

thats because some CD players aren't shock proof. by the slightest little bump the CD player wil stop for a couple of seconds.

Burning of a CD means that you laser write data onto the silver surface of the CD.
You will need an external USB CD player.
'Bumps and Lands' as they are called, is representative of the light and dark spots that are burned into the DVD or CD's recorded surface in a digital format. A 'bump' would be representative of a light (non-burned) portion of the digital word.
No it does not
Gadolinium is durable and is effective in letting lasers burn micronized bumps onto the surface of the disc. A micrometer is one millionth of a meter. This very small raised surface is what enables the CD player to read the disc and play music. Also, an 125 nanometer think sheet of aluminum is sometimes used to coat the micrometer sized bumbs.
This is due to static electricity. When you wipe a CD surface (plastic) with a cloth, it rubs extra off extra electrons onto the CD's surface, thus imparting a negative static charge to the CD.
One can find Bump and Grind by R Kelly on iTunes. The song can also be found on Amazon to buy on CD or Download. It can be bought as a download on Napster to.
