Data storage
Data storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media, some authors even propose that DNA is a natural data storage mechanism. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data. 

Data storage in a digital, machine-readable medium is sometimes called "digital data". Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. Barcodes and magnetic ink character recognition (MICR) are two ways of recording machine-readable data on paper.
