A recording medium is a physical material that holds information. Newly created information is distributed and can be stored in four storage media–print, film, magnetic, and optical–and seen or heard in four information flows–telephone, radio and TV, and the Internet [4] as well as being observed directly.
According to one estimate, one-third of the globally stored information is in the form of alphanumeric text and still image data, [61] which is the format most useful for most big data applications. This also shows the potential of yet unused data (i.e. in the form of video and audio content).

Although location-based storage is widely used in many fields, this was not always the case. Previously, the most common way to retrieve data from a large collection was to use some sort of identifier based on the content of the document. For instance, the ISBN system is used to generate a unique number for every book.
