On an optical disc is an extended pit interpreted as as a series of 0 `s
I think it is am I right ?
Thanks
Yes, you are correct! On an optical disc, an extended pit is indeed interpreted as a series of 0s.
To understand how an optical disc works, let me explain a bit about the basics. Optical discs, such as CDs, DVDs, and Blu-ray discs, use a system called "optical data storage" to store and retrieve data. They have a spiral track of tiny pits and lands on their surface.
When data is written onto an optical disc, a laser beam is used to burn microscopic pits onto the disc's surface. These pits represent the 0s in binary code. On the other hand, the areas between the pits, called lands, are interpreted as 1s.
When reading data from the disc, a laser beam scans the pits and lands. The reflection of the laser beam differs when it encounters a pit or a land. This difference is then detected by the player or drive, which interprets it as the binary code: 0 for a pit and 1 for a land.
Therefore, an extended pit, which is a longer section of continuous pits, would be interpreted as a series of 0s. It is a way to represent binary information on the optical disc.
I hope this explanation helps! Let me know if you have any more questions.
