[KLUG Members] "THE ULTIMATE CD SPEED LIMIT!"

[magoo]

Hello KLUGites! 

Last night we shared a web site that has some pretty 
funny technology information.  Spin a CD-ROM at 36,000 RPM! 
See what happens.    W  A  R  N  I  N  G  ! ! ! 
DO NOT TRY THIS AT HOME OR EVEN AT A KLUG MEETING! 

B E N C H M A R K S :
----------------------- 
My $564 NEC Multispin CD-ROM Reader circa 1993 is a 2X or
double speed and runs at 400 revolutions per minute (RPM).
A 48X CD-ROM drive runs at 9,600 RPM.

Introduction: 
Have you ever loaded a faulty CD into a high speed (30X or higher)
CD-ROM player, heard it spin up to incredible speeds, rattling and
whining, and thought to yourself: "this thing is going to explode"? When
CDs came out they were heralded as the solution for the need for high
storage-high speed information devices, transferring data at a whopping
150kb/s, but like all technologies, 1x CD players quickly became
obsolete as the need for higher and higher transfer rates pushed for
faster players, and, with them, higher rotational speeds. As we advance
into the 21st century CD players are reaching the ultimate speed limit:
we are getting to the point where the CD player simply can not spin the
CD any faster or else the CD will literally fly apart. 

On the interests of the advancement of high speed computing PowerLabs
brings to you:  "THE ULTIMATE CD SPEED LIMIT!" 

===================================================================== 
YES...  A CD DISC WILL EXPLODE!

MORE FUN FACTS THAT WILL MAKE YOUR HEAD SPIN!!!

A DVD's stronger tensile properties mean it can spin at up to 32000 rpm
before serious problems arise, compared to 23000 rpm for a CD-ROM.

A CD-ROM, for example spins from 539 rpm at the inner edge, to 210 rpm
at the outer edge.

TRANSFER RATE
This usually refers to the player's capacity to deliver data. The first
CD-ROM drives were designed to read 75 sectors of data per second, which
means that it transferred 150 KBytes of user data per second to the
computer's CPU. This basic transfer rate is now thought of as 1X,
because current drives specify theirs as multiples of that rate--i.e.
6X, 8X, etc.

WAY TOO MUCH TECHNICAL INFORMATION ABOUT CD & DVD DISCS!!!
