0936012515 is an application field with an associated working principle. In this application field, optical discs, magnetic discs and other media, such as optical fibers are used for data storage. The working principle involves using lasers to read and write the data stored in these media. This technology has revolutionized data storage because it allows for the storage of large amounts of data on a comparatively small surface, thus allowing for the storage of large amounts of data in relatively small areas.

The optical disc is the most prominent medium used to store data within this application field. The procedure to utilize optical discs for data storage involves the use of lasers. A spinning laser is used to create regions on the disc or alternatively an “optical head” is used to read and write the data on the disc. The optical head consists of an array of lenses, a light source and a detector. When a signal is sent to the light source, the light source releases a laser beam which is focused by the lens onto the disc. Depending on the type of disc, this beam is either reflected or diffracted off a region of the disc to create a pattern of alternating light and dark regions. This alternating region on the disc is known as a “bit”. The pattern which is formed due to this dithering of the beam in combination with the shape of the lens is used to represent individual bits of information.

The optical head also functions in the opposite manner. This involves the detector which is responsible for detecting the varying light and dark regions on the disc. The detector then sends this information to a processor which decodes the pattern and translates it into data.

Besides utilizing optical discs for the storage of data, it is also possible to use magnetic discs. This involves the use of similarly shaped magnetic heads in the same manner as optical heads. Instead of sending a laser beam to create regions on the disc, a magnetic field is used. This magnetic field is created by a coil which is wrapped around a core. If there is no data present, the field does not create any regions. However, if there is data present on the disc, the field creates regions on the disc. This is detected by the magnetic head which is used to read and write the data.

The 0936012515 application field and working principle is very complex and versatile. It is used to store and retrieve various kinds of data in various forms. There are many types of discs, optical discs and magnetic discs being the most popular. Both optical discs and magnetic discs function according to the same principles. However, their nature differs as optical discs are based on light while magnetic discs are based on the principles of magnets. All of these technologies are revolutionizing data storage and retrieval.
