How does using a laser pointer to measure the data track spacing on cds and dvds?

First, make sure you have a laser pointer, and a protractor. You'll also need a black marker, calculator with tigonometry functions, an index card, several pieces of thin cardboard (cereal box or something similar), a sturdy box (preferably wooden), and a stack of books.
It's best to work near the edge of a table with good lighting. Anyway, place the CD, label side down, near the center of the workspace. Then put a piece of cardboard to the right of it, and another piece behind it. Both pieces should be about the same thickness as the CD itself. Place the box on top of all of this. If you want to avoid scratching it, put a piece of paper or tissue over the back half of the CD.
You can get the rest of the instructions from the site that my school uses: http://www.sciencebuddies.org/science-fair-projects/project_ideas/Phys_p011.shtml

What component of the computer keeps track of the address in memory of the programming instruction being executed?
A stored-program computer at least needs to know which instruction it has to execute next. Other memory addresses of special significance are e.g. the top of one or more stacks, or addresses to be used by instructions.To keep track of such addresses, all CPUs have one or more registers; for instance the address of the next instruction is stored in the instruction pointer, a.k.a. program counter. Which and how many registers of a CPU are designated to keep addresses depends on the CPU type. The Z80 for instance has a program counter, a stack pointer, two index registers and an indirect address register doubling as 16 bit accumulator, while the contemporay 6502 only has a program counter and a stack pointer.
How does a tracker ball work?
Tracker Ball: A Trackerball is an Input Device.A tracker ball is a pointing device; it is a mouse lying on its back. To move the pointer, you rotate the ball with your thumb, your fingers, or the palm of your hand. There are usually one to three buttons next to the ball, which you use just like mouse buttons.
How fo you make a medley on audicity?
Import your music file into audacity then open another under "project" choose "New Audio Track"Copy and paste your original track into the second empty audio track space which is now below the original track. Highlight the second (newly copied track) and choose "silence"under the "edit" mode. You may now paste a new track into the second "audio track" starting from the end of the now "silent" track. Now adjust chop and change using the two tracks to make your medley. Have a nice day. Steve from Congo

What is peek search on a CD player?
This is when it plays the first few seconds of each track in turn to help you locate the track you want.
Do DVDs or CDs have greater data track spacing and why?
CDs have greater data track spacing because DVDs have more data thereforemore creases or the data track therefore less data track spacing
What is rail gauge?
Rail gauge is the term used to measure the spacing of the rails on a railway track. This term is used in Australia. In the U.S., we use the term track gauge.

What do you measure a track with?

Gauge refers to the spacing between the rails. In the US that's 4'8" and any track spacing that's wider is called "broad gauge".

Widening the track. Also called spacing the wheels.
What if you need to measure long distance?
By using Laser distance measuring devices, work by sending out a laser beam of light and tracking how long it takes for the beam to return to the device. It uses this information to instantly calculate the distance from the laser measuring tool to the object you selected with the beam. Not only does it display distances instantly and accurately, it can track measurements.
What is track ball mouse?
A track ball mouse is a mouse that uses an internal ball to track movement, instead of a laser. These have been outdated by optical mice.
What scientific instruments are used to measure distance?
By size, they would include a micrometer, travelling microscope, caliper, opisometer, steel rule, meter rule, yardstick, tape measure, surveyor's wheel, laser rangefinder, odometer, GPS track, radio telescope, and interferometer.

On a CD is data written in concentric circles or a continuous spiral track?
Based on my knowledge and some research, I say spiral track. I say that since a CD drive uses a laser to read data (that's what I thought and people told me), if it went in concentric circles, then the laser would have to quickly turn off then turn on as it skipped to the next circle. To keep the data flowing to the processor (or wherever it goes, I'm just using logic), it would have to write data on a CD in a spiral track as the laser moved inward to read the data. To me, that's the most logical answer.
