What is a binary code?
A Binary Code is a pattern of 0's and 1's which are also known as pits (bumps) and lands, they digitally communicate information, altogether these are known as Bits.
They are stored on the disk, when a laser hits lands the laser's light is reflected straight back and this is detected by the photocell this is caused by the land, or a number one , however when light fails to reflect back (bump) the photocell doesn't register anything as it realizes that there is no land there.
After this another circuit in the CD player converts and decodes these binary numbers (o's and 1's) into a "changing pattern of electrical currents".
Therefore the binary digits create a pattern which holds data digitally, called the Binary Code, this is decoded by the CD Player and turned into electrical energy and currents.
