All digital data is represented as one's and zero's.
The actual physical representation of data on an optical disc - assuming you are talking about CD's - is called pits and lands.
This article from a 1990 Stereophile article explains much of the mechanics of a CD surface:

What else can I help you with?
Is a optical drive input or output?
An optical drive is an input and output device. It reads data from optical discs like CDs and DVDs (input) and writes data to these discs (output).
What are are thin circular discs made out of polycarbonate topped with layers of materials and coatings used to store data and protect the disc?
Optical Discs
What is the ultraviolet disc and how do they work?
"Ultraviolet discs" may refer to ultraviolet light-sensitive data storage optical discs used for archival backup. These discs utilize a special coating to protect the data layer from UV light degradation. To use them, you need a compatible optical disc drive that can read and write data to these discs.
Is an optical drive an input or output and it's functions?
An optical drive is an input device because it reads data from optical discs like CDs, DVDs, and Blu-ray discs. Its primary function is to retrieve data stored on these discs and transfer it to the computer for processing. So, in a nutshell, it's like the librarian of the computer world - fetching information when needed.
What is optical recording equipment used for?
Optical recording equipment is used to digitally store and retrieve data on optical discs such as CDs, DVDs, and Blu-ray discs. These discs use a laser to read and write data on a reflective surface, allowing for high-capacity storage of music, videos, software, and other digital content.
Why are optical disc more reliable than floppy disc?
Optical discs are generally more reliable than floppy discs due to their resistance to environmental factors such as dust, moisture, and magnetic interference. Unlike floppy discs, which can degrade over time and are susceptible to physical damage, optical discs are designed for longevity and can store data safely for decades if kept properly. Additionally, the data on optical discs is encoded in a way that allows for error correction, further enhancing their reliability.

Which types of optical discs are capable of storing data on both sides?
Optical discs that can store data on both sides include DVD-9 and DVD-18 formats, which have dual-layer capabilities on each side. Additionally, Blu-ray discs like BD-50 can also store data on both sides, utilizing dual-layer technology. These discs allow for increased storage capacity by effectively doubling the available data space.
What is an erasable optical disc?
An erasable optical disc is a type of optical storage medium that allows data to be written, erased, and rewritten multiple times. Unlike traditional writable discs, which can only be recorded once, erasable optical discs, such as CD-RWs and DVD-RWs, utilize a special material that enables the data to be changed. This makes them versatile for tasks like data backup and temporary storage, as users can update their contents as needed. However, they generally have a limited number of rewrite cycles compared to traditional read-only optical discs.
Is an optical drive input output storage or processing?
An optical drive is primarily considered an input/output device. It allows users to read data from optical discs (like CDs, DVDs, and Blu-rays) and write data to these discs, facilitating both data retrieval (input) and data storage (output). However, it is not classified as a storage device itself; rather, it accesses external storage media.
How do discs record information?
CDs, DVDs, and Blu-Ray discs are called optical media for a reason. They use laser beams as a method of writing and reading data. When "burning" data onto an optical disc they engrave microscopic dashes and dots representing ones and zeroes.
What provides data for optical drives?
Optical drives use laser technology to read and write data on optical discs, such as CDs, DVDs, and Blu-ray discs. The data is encoded in the form of pits and lands on the disc's surface, which the laser beam interprets as binary information. When a disc spins within the drive, the laser reflects off the surface, allowing the drive's sensors to detect these variations and retrieve the stored data. Additionally, the drive's firmware manages the data transfer between the optical disc and the computer.
