Difference between CD DVD media
Even though both CD and DVD discs are the same
The size and shape of the media, what they have
Common is finished. There are many different things
Those between them as such they hold
And how long they hold.
Data pits and lasers
The disk has a moving microscopic groove
Along a spiral around the disc. Cd and
Dvd has these grooves.
Applied scanned and grooved.
As you know, digital information
With things and zero. Inside of these disks, very
Small reflection uplift known as land and non-existence
Reflection holes, known as pits,
It reflects both things next to the groove
And zero of digital information.
By decreasing the wavelength of the laser to 625 mm
Or have infrared light, DVD technology
By comparison, I could write with small pits
To the standard technology of CD. this is
Allowing more amount of data per track
Minimum length allowed for on DVD
There is a pit with a single layer DVD-R. 4 microns, which
There are obviously more than .834 microns that a

The track of the DVD is narrowing as well
To track / disk,
It converts to capacity rather than CD. this

While the CD holds just 700 MB.

As mentioned above, the DVD has small pits
We need to pay attention to laser. This is actually
Realized using a thin plastic substrate
More on the CD which means that the laser needs
To pass through a little thinner layer
The depth to reach the pit. That is this decrease

CD.
Data access speed
Dvd accesses the data at a much faster rate
You can do CD. I read an average 32X CD-ROM drive
Read 4MB of data, 1X DVD drive
With 1.38 MB seconds. This is even faster than
8 × CD drive.
Generic data format
There are quite a few recording formats of Cd and Dvd
Dvd is different like using UDF, or universal
data form. Data, video,
Audio, or even a combination of all
It is stored in a single file structure. this
You can access arbitrary files for this
Drive, computer, or consumer by video.
On the other hand, cd is incompatible with
