Optical storage device
This type of storage is called optical storage. Data is stored by encoding information as microscopic light and dark spots on the disc surface, which can be read by a laser beam in devices such as CD-ROMs, DVDs, and Blu-ray discs.
Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
The dark spots on the Sun's surface are called Sunspots. These are formed by the sun's magnetic field because these areas have less convection underneath the sun's surface. Convection is how the sun's energy gets to the surface from the core in a circular motion. This reduces the heat in the area and makes the area appear darker than the surrounding sun. However, these spots are still extremely hot and can be many times the size of Earth!
Dark areas on the surface of the sun are called sunspots. They appear darker because they are cooler areas compared to their surroundings due to strong magnetic activity. Sunspots are temporary phenomena that can last from days to weeks.

They are called sun spots, dark areas that are cooler than the rest of the surface.

The black spots on the photosphere of the sun are called sunspots.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb.

Dark spots on the moon during a lunar eclipse are caused by the Earth blocking direct sunlight from reaching the moon. These dark spots are the shadow of the Earth falling on the moon's surface, which gives the moon its reddish appearance during a total lunar eclipse.

Dark spots in the ocean are areas where there is a lack of phytoplankton, which are tiny plants that float near the surface and provide food for marine life. These spots appear due to factors such as nutrient availability, temperature, and sunlight levels, which can affect the growth of phytoplankton.
The dark spots on the surface of the moon, known as lunar maria, are caused by ancient volcanic eruptions that filled large basins with basaltic lava. These lava flows solidified to create the smooth, dark areas that we see on the moon's surface.
