Answer 2

Answer:

The data on a DVD is held in the form of small pits and bumps on the disc.

Explanation:

• DVDs share some of the same materials and production techniques as CDs and have a similar width and thickness.
• Similar to a CD, the data on a DVD is stored as minute ridges and divots in the disc's track.

• A DVD is made up of many plastic layers that together measure roughly 1.2 millimeters thick.
• Polycarbonate plastic injection molding is used to produce each layer.
• A disc with microscopic bumps arranged as a single, continuous, extraordinarily long spiral track of data is created as a result of this procedure.
• Instead of bumps, you'll frequently read about "pits" on a DVD. On the aluminum side, they seem as pits, while on the side the laser reads from, they appear as bumps.

• The spiral track on a DVD is very long due to the bumps' minuscule diameters.
• The data track on a single layer of a DVD would be almost 7.5 miles long if you could lift it off and stretch it out in a straight line.
• A double-sided, double-layer DVD would therefore contain 30 miles (48 kilometres) of data.

• You need an exceedingly fine disc-reading technology to read bumps this minuscule.
